The people on the other end of this line had Indian/Pakistani accents, and were calling from a very crowded room.  They claimed I had earned a lower interest rate on my card, and seemed to be trying to get information from me.  People who receive a call (in Canada) from this number should contact +1 888-495-8501, Phonebusters, the Canadian national agency created to deal with phone scams.

They almost had my husband.  However, I did a Google search on the phone number (250) 980-3438 Ex 299 while my husband was on the phone to them and found that is was a scam.  

The names given were Tony Adams and Kevin Austin. They also gave a toll free number 1-+1 888-628-9228.  The number that showed up on my caller ID was 1-(403) 648-9228. They are very persistent, even after hanging up on them and telling them to stop calling they called back within 10 minutes.

Should they call you do not give them any information about anything.  Tell them to f*ck off and hang up on them.

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!!!

same thing as above.. it sounded like a really crowded call centre.. they were offering me a lower interest rate. i just hung up on them. they keep calling.

Credit card consumer advocate called with caller id of (250) 980-3438 with same offer of reducing interest rates on credit cards.  Could hardly understand him and he said he would call back.  2 minutes later called back showing a (647) 288-1289 area code id and went through the spiel. I told him I would not give any information over phone and that I would check out their info and call back if I wanted to pursue anything.  He gave me a Alberta area code number (403) 648-9228.  I could not find these numbers on reverse directories so with what they are asking for it would be wise to rebuff them. This guy gave the name Oscar Smith.  Nice non-descript name for a guy that speaks english with a heavy east Indian accent.

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