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?"

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.

This is a scam!  They're just looking to steal your credit card info - do not give any info out.  If you ask to be removed from the call list they just hang up or cuss at you and keep calling back.  I am on the Do Not Call list, but it appears they could care less.  They're either re-routing through an international line or spoofing the number so it cannot be traced and the telemarketers cannot be prosecuted.  Phone company can't do anything or block number because it is an 11 digit number.

Same deal as Greg.  What can be done about this?
