i also received a call from this number but i never picked up the phone

My mom got called this morning. Credit Card Companies don't call you to lower your interest rate, thank you Opera and any other talk show that talked about finances. My mom had her credit card to look for the customer service number and it was incorrect so my mom said she doesn't want to do this over the phone and her credit unions will do it for her when she's in person.
What buggers using that number in Ontario. Hence why I never pick up numbers out of province.

Just got a call from (647) 288-1289 saying they were calling from Mastercard to lower my interestrate. I asked who they were looking for and they gave me Mr or Mrs Jenkins. I said this is the wrong number and nobody by this name lives here. They said who am I speaking to? I told them you have the wrong number and dont call here again.

Got a call while doing baking and didn't answer.  Came to the computer to see where the number was from.  Thanks for posting this.

got this call today.  i hung up as soon as they asked if it was true that i pay my balance on time.  

creepy.

Received a call from them today. that's about interest on credit card. This is a scam.
