Bad service and bad attitude

On the 21 August 2017, I went to a multichoice accredited installer in mdantsane city to pay my dstv account, a month later my account was disconnected because I was owing some money according to them. Onlybto find out the person who helped me with my payment upgraded my account from Compact to a Premium without my concern, that is why I was owing, now from August I have been trying to have this issue resolved as it is now inconveniencing me as my account gets disconnected everymonth. The worst part is that Siyanda Zazini who is the person who upgraded my account says she can't help because it's not her but the system that upgraded my account.what nonsense is that? Even though other stuff tried to help me which didn't make a difference because the account still gets disconnected.
