Telkom, literally customer service at it worst

I have upgraded from an ADSL line to a Fibre line in November of 2017 and signed a 24 month contract with Telkom for R999 per month. The salesperson at the Telkom shop in Mall@Reds assured me that I will only be paying the amount mentioned above with NO additional costs, however at the start of January 2018 I was billed nearly R1500 each month for November, December and January. I attempted to log the query with Telkom 3 times to no avail. After the first attempt I did not receive any feedback, after the second attempt I did receive feedback and was told that a dispute was logged however this was also a blatant lie as I received no feedback and when I did manage to get into contact with another consultant, she did not even see any dispute that was logged. Finally I logged yet another dispute and after a few weeks received an SMS notifying me that the amount due was still over R2800 while it should have only been R1700. The service I received from Telkom was absolutely pathetic and the employees at the store are no help at all because they do not have access to the billing details of customers.

In short, the customer service from Telkom has to be the worst I have ever experienced from any company and it seems as if they only care to communicate with their clients when they are seemingly owed outstanding amounts, otherwise no effort is made whatsoever to ensure client satisfaction.
