dstv/multichoice customer service is pathetic, they are the worst!!!

Dstv is advertised a deal where you pay an extra R100 and your current package will be upgraded to the next package. I am an Access. I paid R100 on 1st April, today my Access has not been upgraded. I have so many calls and sent so many emails. On the calls, I get put on hold endlessly until I give up. There is no response to my emails. Now I see that the R100 has been allocated to next month instead of being used to upgrade. This is so upsetting, so much of my time and airtime has been wasted. dstv/multichoice customer service is pathetic, they are the worst, no wonder they are continuing to lose clients, soon they will be losing me!!!!
