Appalled by poor service and communication

For the past two years my Dstv account has been double billed on my two devices I have on contract. When the offer on the two devices were made, I asked them over and over again will the debit only be for the devices as I still want the option to change my package. They over and over again said yes. A year into the double billing they start deducting my prepaid subscription out of my account without my consent. Eventually my subscription is disconnected, not the first time and every time I have to pay money in. After phoning on several occasions with no solution I decide to go in to multichoice, where my husband's phone is taken by another client. The security gets the phone and let the ***** go without the option of phoning the police. After this my money gets reversed my account is good and I even give permission so they can deduct the prepaid out of my account. For one month my account is billed correctly and after that guess what, again with the double bills. Last week I reversed my monthly installment and went into multichoice once more to reverse my money which they did. After which I asked are they sure the problem is solved and I was promised it was. This morning my account is suspended because I did not pay. My husband is currently standing in the rain again at multichoice after I phoned and I was told to hang on. All the airtime ran out and no solution. I am appalled by the poor service and I have had enough.
