Just got a call from them and they left a message but didnt ask for anyone or give there business name they just said if I dont rectify this matter they will take further action, so of course im not going to call them back and if I ever do answer the phone to them I can be just a intimidating as them

are you guys using rogers? I am. if so it might be someone from inside Rogers.

Started to get calls from them today. Answered them and they said I owe $300 to rogers. I told them i am up today with my bills. They told me to call rogers which i did and Rogers verified that i am up-to-date with all my payments and that I have never had a late payment with them. The people from the agency even verified my date of birth and address and said it was me they were looking for. They just keep calling my cell, very annoying.

To stop receiving phone calls you have to mail in a letter ( registered mail) to tell them to stop calling you at the home number. Every month you must do this. If they call you at work, it takes one time only for you to tell them to stop calling you at work. You can make a complaint if they should call you again. Legally, they can call you 3x a day. Can't call on Stat Holidays. Every province has a time they start from and finish at. They can't impersonate anyone, they can't speak to anyone but the debtor, they must identify themselves and where they're calling from.
I used to work at NCO Financial doing collections for Telus Mobility and Rogers. In all reality guys, there is a cancellation policy regardless of whether you like it or not..its a contractual agreement and its unfortunate that no sales people tell you about that part of the contract. I don't work there anymore obviously because I found it to aggressive. I was one of the nice people that would actually work with you rather than fight with you...Read up on your collection laws in your province and find out what your rights are. (And maybe review the contract you signed as well) The CSR should do a financial statement with you to see what you can work out. Their first demand is always payment in full but did you know you can ask for a settlement amount? that would have to be paid in full. Did you know that if you send them $20.00 a month and make your postdated payments via your bank and provide them with the reference numbers, they'll stop calling. They can't refuse a payment so don't screw up and miss one lol
Good luck....just a few helpful hints...

they call every morning afternoon and evening - does anyone know who they are?

They are a collections agency.  Just ignore them.  It doesn't bother me in the least.  Lol.  They can call all they want.  The best part if you ignore them for 6 years, the debt just goes away.PS.  You should post their number in every classified ad online and fill out every ballot for every contest (which is really a way to get your info for other telemarketers) at supermarkets and elsewhere. Hell, post their number in sex ads.  Let them enjoy their number ringing all the time.  hahahaha
