I received a call from this number. I did not answer but called the number back a few minutes later. The message gave the option to press "1" to be placed on the Do Not Call list.
This call is from "Heather at Account Services" calling about my credit card account (did not specify which card), said that this was my LAST CHANCE to qualify for lower interest rates, and "press 1 to be connected to a live operator".
Called left no message. But from looking at the posts here I vote for spam or in the immortal words from Pulp Fiction Prank Caller, Prank Caller, Prank Caller.
"Heather" called from this number yesterdat for whatever the scam of the day happened to be. I blocked the number, but "Heather" called me for a different scam today from a different number (also now blocked).
