Claimed to be calling on behalf of my bank to lower my credit card interest rates - did not have the name of my bank so I knew they were a robo-call / telemarketer. Would not give me their name. Obvious sounds of telemarketing "bullpen" in background - sounded like an overseas call center, too, routed through a local number. Told them to remove my number from their list.
I received a call from here this morning and they were wanting to lower my interest rate on my charge card....but they didn't say what the name of the card was and it sounded like a recording type message. I didn't press any numbers to go on with the call I just hung up. I'm pretty sure it was a hoax of some sort.
