Double Charge For Data Bundles

I was charged for 10 gigs of a free me bundle 3 times on my November billing. I tried to purchase a once-off 10 gigs free me bundle on my App and it was not working. I then called the Call Centre and asked the Consultant to load it for me on their side and they told me the system was down and they would do it for me once the system is back online. Off course the Consultant did not do anything! I had to call in again and spoke to another Consultant who informed me that nothing had been loaded but again could not load it as the system was still down and they would load it as soon as the system was up. To my surprise the 10 gigs was loaded as a recurring data which I did not ask for. This meant that I was now charged for the recurring in advance, which was R399x2. It was explained that recurring data is charged for in advance-understood, although I did not ask for recurring. But to my surprise I was charged another R399 on the same number, meaning I had to pay R1197, an over charge of R399. I logged my query with Telkom Mobile beginning of December and was told it takes them 72 working hours to revert back to customers on queries....Big Lie again! Today is the 31st of December and there is still NO COMMUNICATION nor RESOLUTION from their side. Can someone please tell us what needs to be done to get service from this crowd???
