Unhappy customer

Customer number- ***4

I'm not happy with DSTV. I found that one of my Access subscription was upgraded without my knowledge to DSTV Family. I did not upgraded it and I was debited and now they refuse to give me my refund. DSTV told me that maybe another person upgraded it. If I didn't upgraded my package who can upgrade it without my knowledge? DSTV is pathetic in dealing with customers. I think it better to watch SABC channels and forget about their repeated channels.
