I had the same crap call from (905) 595-8640 for lower rates credit cards.But another strange thing is that 4 days before, I had another call from 979 446-0366 saying I won a trip to Orlando for $2200.Im pretty sure they are the same scammers.

I got a call from them yesterday.  They said I one two trip because I passed 3000 point with my air miles.. He had a heavy accent and said his name was Robin Gibbs.  Sound convincing at first because it sounded like a busy call center and the phone number showed up on call display.. I gave him my birth date and code on back of my master card.. He then asked for the last 3 blocks of numbers of my mastercard. The first block is the same on all bank of Montreal mastercards.. That was not going to happen.. He also said that I would have to pay the tax for the trip $499.

Yes to add to the other comments my elderly, widowed mother has been scammed also.
They offered her a holiday to Mexico. The person that spoke is Sam Anderson. I have reported it on the website below. So far I have been unable to get their exact address. But I believe they are in Carrollton, Texas (which does seem a bit strange given the accents and that previously they said they were in Georgia).
Take care everyone.
(another number they told me was
0012034127273)

OMG! You are so full of crap! You lie! YOU are just one of the many thick accented 'Patels' pretending to be a 'Warner'Doing nothing more than wasting people's time and/or money.

Got a call from Angel Rick, he said because our account was in good standing we had won a all inclusive trip for four people to Cancun and Orlando, Florida plus they were giving us extra rewards points.  He said he had all our credit card info and when I asked what our credit card number was he did have the first four digits but said he couldn't give us the rest since this call was being recorded and the privacy act wouldn't allow him to.  When asked the whole credit card number he would not give me that info but had our address.  Then he wanted the number on the back, he said this was a branch number and not a security number.....no I didn't give it to him.   I called Visa and they put me through to the fraud squad....  So our card had to be replaced......NEVER GIVE OUT THE NUMBER ON THE BACK OF YOUR CARD.

I also received a call from this number today and was equally disturbed.

An indian male claimed to be from Visa and wanted to lower my interest rate based on payment history.
I flat out said I don't believe you are from Visa, quoted his phone # and demanded to be taken off his list and promptly hung up.
