i received many calls from this company and was considering to put down my rates. they knew my balance and credit number of both my cards

the name was joel joseph and gave me the number (403) 648-9228

Warning!!! These people are scamers. They called me yesterday and offered to lower my credit card interest rates from 19.99% down to 6.1% for life. When I told the guy that I like to call him back and asked for his number and his name he told me the number the number you see on your call display and said his name was steve daniels. I knew he was lying so whe we hang up I called him back and this number was no good. What a scam. Advice: If you are not sure what to do in this situation or similar situation, always offer to call them back and never give any information like expiry dates etc...

This number called me and when I didn't pick up, left a mumbled and brief message. NEVER CALL AGAIN!
I am also on the DNC list but obviously that doesn't help much.

We get called several times a day, and have for years. They want to get your credit card or personal data for some scam product or service. If you answer tell them nothing and hang up. Asking to be taken off their list, or threats go nowhere.

Don't waste your time getting frustrated.

They use spoofing software to fake any phone exchange in the world. They use a dialer to call hundreds of numbers at the same time.

These are the morons that should be prosecuted. They say it's great for professional people to protect their identity - but we all know the scum that use these services/software.

These jerks could be anywhere - likely some 3rd world country where no law can reach them. Don't answer and NEVER expect them to stop.

They won't.
