TELKOM Another Eskom

about 5 Months ago I moved away from ADSL to LTE. First two weeks I had no issues ,top speeds etc. After that I started having issues during peak time from 6:00PM to about 11:00PM my internet speed suddenly drops,becomes intermittent and takes ages to load a basic webpage.It goes to a stage were there is no internet at all. I Phoned telkom ,reported the issue a few times. They sent a technician on site during the day to test the issue, he did some speed tests ,saved that info and left. I receive a call a month later (still having this issue) saying that the technician came onsite ,it was raining (it was not) did the tests and it seemed fine ( It was during the day, the issue is in the afternoon) but did mention something about tower overload. Anyways the issue has not been resolved till date , I cannot cancel the contract because they have a clause to pay up close to 2.5k before contract completion and still have not received any sort of solutions from TELKOM. #TIREDAF
