Back and fourth with no conclusion

In the second week of June I was told my 24 month 20gb LTE contract was coming to an end and that it would now be on a month to month basis. I asked to be upgraded to the 50gb package as it was the same price as what I was currently paying and was told to go to a telkom branch where they would be able to assist me. I went to a telkom store and they said they couldn't help me and logged a call, the case was then closed after one call without any conclusion other than I was still on 20gb a month. Went into the store again and another call was logged, which again has not come to any conclusion. I spoke to a lady named Maxine that said she was going to escalate it to management and I am still waiting .... been well over a month of going up and down with no help from anyone, just people shifting it onto someone else. The amount of frustration this has caused is completely unprofessional and unacceptable. I'm not one to complain, but really this is quite pathetic service
