Overcharged - 9 months

Signed up for Do Premium (Do Level 3) which includes my 10mb adsl line, 50GB data and line rental for R699. When the first bill come, there was an overcharge. To keep the story short, I have phone and a query was logged and I received a refund. 2 Months later the same problem, then i went to the store where a dispute was logged, @ month went by with out problem and once again the same problem. This is been happening since the contract was signed. Since the 22nd of February 2016 I have been in contact with Telkom via their twitter account. I have been made aware that the account was escalated and someone will contact me, then 2/3 days goes by without any feedback. Once asked they apologize for the delay and someone will contact me. I have been waiting for feedback from the 3rd of March where i keep on send requests and no feedback. I was told that I should be patient. 9 months i think is patient enough. I am being told now that there is a problem with the system and that IT is included in the escalation to get this resolved. In the meantime I'm being called by telkom sales for tables on a daily basis. Who want to take this if you are constantly having problems with BILLING.
