Apology does not sort out MY PROBLEM TELKOM

I logged a call on the 5 th November 2019 in regards to my LTE mobile being slow....with an upload and download speed of less than .05....endless follow up calls have been made to be advised that they are working on the problem.....They are quick to apologize as they are trained to....however this does not help the cause....I run my business from this line and am more down than up....then when asking for feedback....we are working on it...IN ACTUAL FACT THEY COULD NOT CARE A DAWN........LOG NO ***.....etc......Please do not use telkom....we moved from a fixed line to THEIR mobile service as they could not sort the cables out....now THIS....WILL have to wait to move once contract expires.....
