Worst accounts service by far!!

Dstv keeps on suspending my service. In July it happened the first time. I called them and they confirmed that my account had a credit. They reconnected me but 2 days later the same. This happened about the 20th to the 23rd. After speaking to a call center manager the problem was resolved and my next debit date and amount was confirmed. Come the 2?d of August dstv tried to debit me by more then double the normal subscription. I reversed it. I paid an amount which the confirmed to be active till end of August, but now every second day my services are down. Somewhere they decided that I never had a credit for July and that I had free TV. Now they can't find there mistake. I went to a branch and next to me was a lady with the same problem. I must say that dstv with their new systems are useless. After spending between 2 - 4 hours on the phone with them still no answers. I asked that a manager contact me, I am still waiting. I expected good service from this company as they are getting good money every month. But now its like alot of other things. We pay for service which we will never receive. Well done DSTV.
