I had the same thing happen. I mean if the credit card company wanted to reduce my rate because I pay off my credit card in full they'd just do it. They would also know the information they are asking for. And they always ask for confirmation question to make sure it's them. Plus they are asking for more then one of your credit cards, this means they are NOT with the card issuing company and they can't possibly be from your credit card company. Also, did a reverse look up and it's a land line in British Columbia, Canada it appears to be through Telus. Obviously NOT a REAL call center! THIS IS A SCAM BEWARE!!!

Got a call from these clowns today.  I now just say sorry that person is not at this number and hang up, fastest solution.

Got a call from (250) 980-3438 telling me they were going to reduce the interest rate on my credit cards - my visa and mastercard. They obviously had no idea if I have a credit card, and if so, which one it is. (They're hoping you'll tell them). When I asked them who they were (several times) he rambled off the name of several banking institutions, hoping that I'd recognize one and trust him. WHAT A SCAM! He also told me that he was calling from CCA. I asked him what that was, and he kept repeating CCA. CCA. I finally asked him what those letters stood for and he said Credit Card Advoctes. I told him I was NOT interested and hung up on him.
He had a very thick accent and it was really hard to understand him. There was also lots of talking voices in the background, like if he was in a crowded telemarketing center.
I will be reporting this number and adding my phone number to the do not call list.

Took a while to hear anything - sounded far away - heavily accented voice - couldn't understand - when I said pardon me they cut the connection.

Somebody called me from (250) 980-3438 on Feb. 08/10 9:50am in Calgary telling me that I owe 100K on my visa and asking me about my and my husband’s visa statement. After I told that I don’t know my husband’s statement and that my statement shows $0 balance they hung up on me.

They were a group of people from India trying for my credit card numer..F****d up bunch!!!!DONT TRUST THEM!!
