Didn't tell the company name until I asked, then told me "Account Services".

"I've never heard of you guys, where are you based?"

A new credit card group that wants to lower my rates with a threat this is the last chance (of course 10 last chances in a months or so). Another moving target so I now follow their instructions to speak to an agent who can help me. I then go into my disabled voice (shouting Helwo, helwo, can you hep me?), this usually goes on for about 3 minutes, I am now starting to enjoy this routine and may add some more to it. Have fun, take up their time.

Didn't answer when I saw the number.  I too noticed though that it had too many numbers.  506 is the international country code from Costa Rica.  I don't know if this is where the call came from (this is also the area code for New Brunswick, Canada).  I'm sure whatever they are trying to sell is a scam.

I have called my carrier (Comcast) and they cannot do anything about the 506 number which becomes a moving target, so I cannot block them all. The problem is they fill up my answering machine when I am gone, so after all my futile efforts. I now transfer to a live person, waste their time and sometimes become very rude in explaining I am currently on the toilet and ask if they would like me to explain what it looks like. My goal is if I put them on speaker and waste their time, at least it cost them something. I am frustrated that Comcast and the Do Not Call Registry can do nothing. HAVE FUN WITH THE IDIOTS.

I've told them I'm on the do not call list and asked them to take me off their list several times now. They keep calling me. Wish I knew who they were so I could pursue further action.
