Poor service

Hi So dstv refuses to reconnect my service because all of a sudden my account is under investigation, before this I was told to pay which I did now they say something is wrong and dsyv had confirmed they got my payment so no one had any answers to why this ended up here I can't even call in they ask for a business number which I don't have my decoder is messed up and they can't help me no one wants to call me and explain I'm so upset with this service!!!
