Charged for 2 packages

On the 6 June I requested my DSTV packaged be downgraded to the DSTV Family package from the 20 June, on the 08 June I received confirmation that my instruction was actioned . On the 20th the full Premium package amount was deducted from my account when I queried it with DSTV the consultant said my package was only changed on the 21 June and I'm currently on two packages and that I still owe DSTV +R420, namely the Family and Compact package. I didn't even know it's possible to have two packages. I checked the channels and it only consists of the Family package . I would like the Compact premiums to be reversed and would like to know since when do you charge 2 months premiums in advance as this is another first for me. I requested a simple instruction to be executed and I must say I'm utterly disappointed for the inconvenience I'm going through . On the 6 July I asked if a consultant can give me a call and I'm still waiting....and waiting.....and waiting.
