Telkom disappointing servive

For the past few months Telkom's fibre has been fantastic. Since yesterday, however, their fibre service has been **********ly slow and totally inefficient. Yet, as the end of the month approaches, they will deduct their normal fee. This is totally unacceptable and I am now considering terminating my contract with them. They are aware of the problem in Eersterust, yet they will not even send an SMS to notify us that they are busy solving the issue. This has happened before. Their assistance, when you phone their so-called 'helplines' are just as ineffective. I have reached thed the end of my patience with Telkom!!!
