Had a few missed calls from them where they call once and hand up.Presumeably,  calling them back will be at international or premium rates.

yes it says on my phone its from ontario

They called this morning asking for Mrs.@#% and I said I am Miss @## He said sorry about this. I am calling because we see that you have made your credit card payments on time for the last 6 months and you have been approved for a 6% interest rate credit card. I told him at that time that I did NOT have a credit card and to remove my number from their calling list and then hung up.

I just recieved this same phone call. According to RCMP here In Alberta it is definately a scam and you should monitor your account and the activity. also contact your bank and report it through your bank. if we all band together we might be able to get these people closed down.

I have received a few more calls and he now has the gumjpsion to leave vulgar messages on my answering machine. He has called me many times now in the last 50 minutes.

I'vehad the same call from this number on numerous occasions. I recommend calling the local city police/ fraud division.
i recommend not gbiving any information to them at all, verify the number calling you forward it to  your local police division
