DSTV service sucks they don't know how to treat customers

Early last month I deactivated my account n when I called I requested to cancel the dstv stream and the insurance that I had with them and the person that I spoke with confirmed the cancelation for stream and after I requested to downgrade from compact plus to compact and I was told to pay R499 of which I paid n few days later they debited again and I reversed that transaction cause I already paid and on the 28th of March I app**** for price lock and it was approved and the package was delivered on the 31 of March and their technician installed the decoder and linked the account with my previous account but to my surprise my account has been suspended and when I call today the lady that I spoke with said on their side it shows that the delivery is still pending and when I ask who delivered the package they are telling about different company and I'm confused cause I was transferred by one of their consultants to the department that deals with price lock and now my account is blocked and I'm told to pay - +R450 but I already paid for this month. Even today I called them 3 times and the only they are telling is to pay n I'm not getting any assistance with the price lock that they delivered
