Vasmartt are **********

I got a call from *** and was told I owe Multichoice money. I have cancelled my DSTV account over a year ago and have never heard from them again. Following the call, I received an sms with their banking details. I called Multichoice and asked them about the outstanding amount and was told that I owe them nothing. When you call back on the 087 no you get a message to say you are in line and then the phone goes dead................no one answers. This is *****!!!!!!!!!!!
