13 Calls to Multichoice in 2days & no assistance

I called multichoice on the 28/08/2015 to get my Dstv activated. I asked hoe much i needed to pay and was told R1116. I went and paid that amount called back to get the DSTV package downgraded and activated they told me my payment was not reflecting on their system and that i had to send proof of payment to which responded saying that email longer exists. I spoke to an adviser who told me that they can not down grade my package i will have to wait another month and pay more than the initial amount end of September i said NO no one advised me of this and asked to speak to a manager no manager came to the phone the adviser told me that their team leader activated my dstv and down graded me never happened. I then checked my self service check your balance and it said i was outstanding with R2996. i called again and spoke to a manager Kgomotso who assured me that she had escalated the matter and raised a case and that she would call me back which NEVER happened today is Tuesday. I called the centre again to speak to a manager and was put on hold for 50min jst for the call to be cut and no call back (Mansu Zwandi) the adviser . I am fed up annoyed and ready to take legal action. USELES
