Multichoice's bad customer service

I've had the worst experience with Multichoice. I tried doing change of ownership on my decoder unfortunately it was rejected due to the account not being paid. I paid the account in full only to find that my decoder wasn't playing so I called the call centre they said my decoder was registered on another name of a person that I don't know. They told me to find that person (keep in mind) I don't know that person. So right now I can't watch TV because I have to find a person I don't know. I'm really disappointed because i went to two of they're branches and they couldn't help me. When I ask them to call that person (since they have the details) they said they can't. I believe that I was judged by the staff at the branches they think I stole the decoder which I find to very offensive and upsetting.
