Poor Service from DSTV (MultiChoice)

I am very disappointed at this company, their customer care needs proper training, I was told to go to walk-in center in Randburg, off which I did, and when there the person by the name of Lerato Selepe only send an email and my account was not activated even today while they debited an amount of R820 which shows as credit in my profile, I have seen poor service but this one is worse, especially when customer care consulted give different information some of them don't even know that the walk in centre in Centurion is no longer operational, it simple means I need to dedicated half of my time every day just to deal with DSTV while they don't want to activate my account. I have made it clear to them that I no longer want to continue with their services they should just refund me, and now I am told to go back again to the walk-in centre, this is kind of a pathetic service that will make a company to slowly lose customers....
