Bullies - Norman Bissett and Acc.

Whether a person pays them or not, you still get harassed and threatened. I stopped paying them for my Getbucks account, VerTex then started collecting from me, with no harassment and zero threats, I have been paying them religiously, YET Norman Bissett and Acc, STILL CALL ME at least 2 / 3 times per day, and send me threating messages, trying to collect for the same Getbucks account. How on earth does 2 collecting agencies collect for ONE outstanding account.? I refuse to deal with Norman Bissett and Acc, they are bullies and ruthless, and I have had enough of them. My next step is legal.
