Lack of customer service from Telkom

Lack of customer care from Telkom

I have been dealing with suppose to be a supervisor her name is Gugu Mashome for a couple of months now trying to sort our my Directors Telkom mobile account. Last year December 2017 my boss renewed his cell phone contract. Since last year he thinks his been using his new contract package not noticing that Telkom was billing him for his new contract as well as his old contract. We only noticed in July that this was the case. Ever since then we have been sending emails to Gugu, who is just not sorting out the problem or giving us our refund, until today every month they still debiting from our company bank account. Gugu sent us to buy a new sim card, but nothing so far has been done to keep my Director happy. I am his PA and he has been asking me everyday why Telkom has not gotten back to me yet or sorted out this problem. Their lack of customer service is really ridiculous. My boss now wants to take legal action and to change networks as they keep on deducting for the new contract as well as the old contract and nothing is being done to correct this problem.
