Terrible service

I logged a call with Telkom on 06-09-17 16:58 for my uncapped internet, where the speed has deteriorated over the last three months. It has become so bad that only one person can be connected in order for anything to work properly. I was sent to a Telkom store to get the router tested. The router tested fine. The employees in store basically checked my account, reset my router settings back to default(as it has always been) and got me to do a speed test on my phone whilst being connected to the router. This was the extent of their "technical" teams investigation. Basically everything I have done at home already. On the 4th of October I called Telkom to get an update. The lady could not provide any update because none has been provided on the system, in other words absolutely nothing has been done for the case I logged. On the 17th of October at 22:59, I got a message update stating "Good day. Note that your case is still in hand with our Networks Department, Further updates will be sent in 7 days. Regards TM-SOC, Telkom Mobile." It is now 22 days later and still no updates. On the website it still only shows as "Logged 06-09-17 16:58". Telkom provides the worst service. No updates provided and even when you call for updates, no updates can be provided. Not sure they should be called a "help" desk as they don't provide any help other than redirecting you to the store or giving you information such as the call is with another team that is taking care of the investigation. I am quite sure this complaint will be dealt with in the same way as my original call I logged with Telkom.
