Scam FYI:
Do not be fooled by scams/extortion attempts!  If you feel you are being scammed, hang up (or tell them off first if you feel like it; telling them you're going to call the police usually causes them to hang up), use *57 to use Call Tracing on the last received call, then call the police using a non-emergency number.


Debt/IRS Scammers

One IRS scammer that is particularly persistent is one that is going to show on your caller ID as GILA CORP with a 512 area code (notice list above).  Once you get on their list, they will call you every single day (at least they have with me since I got the first call) & blocking one number usually means they call back on another number in the same area code.  Your best bet to deal with these assholes is to use Call Tracing (see Scam FYI) on their calls every time they call & block each number until they run out of numbers; some providers will allow blocking of partial numbers (a form of wildcard entry), which may allow you to block all their numbers with one entry, but make sure you don't know anybody with a phone number in that range of numbers before you block it.
The scammer from phone number (844) 890-9215 used some very aggressive pressure tactics threatening lawsuits, prosecution & jail time, even stating he had my social security number.  This was one of the few cases where the police was called afterwards.  Almost a month after the last verbal assault, he started calling my number again, as indicated by my Comcast Missed Call log (which is where they go directly to when placed on Caller Rejection).  Despite the fact that he's getting a Caller Rejection recording when he attempts to call, he's still attempting to call almost every day only to get the same message, either not understanding he's been placed on Caller Rejection & won't be getting through, understands he's been blocked & thinks I'm going to remove it (which perhaps I will have to when I run out of slots, unless I purchase that 1000 number external Caller Rejection device) or he thinks it's a bug/joke & he will eventually get through.

The calls stopped for about a week, then I started getting calls from (844) 890-9217 with only a one digit difference from the last one.  Given the numerical value of the number is only +2 & the Caller ID still reads 800 Service, I expect it's the same scammer.  To verify this, I did a number of searches online & there was a number of sites stating it was a scammer, although details were vague as to what the scam was about.  Regardless, I added the number to my Caller Rejection list & decided I needed to list the number even if I didn't have the details of what scam he was pulling.

The situation regarding these calls have gotten bad enough that I decided to file a complaint again the most recent number (including details about the previous number) to the FCC, hoping that it will at least halt the calls to others, as this lowlife is already on my Caller Rejection list & the only indication I have that he's still calling are my Comcast Missed Call logs.

Much like the last 2 numbers listed here, (866) 490-5501 also had the caller ID of 800 Service when received on 2/16/2017 at 1:21 PM.  It's very possible this could be the same individual & return call logs from (844) 890-9217 would likely verify he was using this number to probe whether the line was active or not.

Again I received another call where the caller ID read 800 Service, this time from phone number (800) 864-7459 on 3/2/2017.  I didn't pick up on this call (regardless of being right next to the phone when it rang) as it's my experience that any time the caller ID reads 800 Service, it's going to be this same scammer.  Checking my call logs on Comcast, I found that he tried to call me 5 times at 11:40 AM on 2/28/2017 (displayed in take 2 below), which all got blocked by caller rejection; this call was likely another number to try & probe whether my number was actually active or not.

The phone calls from (844) 362-9238 appears to also be from this same individual, following the same sort of callback pattern that (844) 890-921# had.  This lowlife keeps changing his phone number trying to get past phone number blocks, but so far hasn't realized it's just going to be the same pattern every time I see 800 Service on the caller ID.

Scammer return caller logs

Scammers are very persistent, continuing to call you over & over again regardless of whether they've been placed on caller rejection or not.  After the situation with (844) 890-9215, I noticed he was still attempting to call every day despite being put on caller rejection & started logging his callbacks from this point on.  On 9/29/2016, I decided it was time to start doing this with other numbers that were attempting to call back also after they were placed on caller rejection or I had told them off previously before hanging up on them.  This list can be found below (for what I have records of), click on phone numbers to see a screenshot of the logs from my Comcast Voice logs:
