Telkom - from bad to worse

I signed up for R599 Uncapped fibre deal with Telkom. We called them out several times because of the poor download and upload speed. My husband could not work from home and neither could my son do his E-learning course. it is still not nearly the 4MBps deal we signed up for but Telkom is clearly not going to fix it. We are still unable to download movies etc. When I signed up for the deal I was told R599 per month only. Now in the first place I am reluctantly paying for a service which I am clearly not getting nor never will. But to add insult to injury I have now received a statement of account for R910-50. When I called Telkom they said it was a reconnection fee and I missed a month's payment. I disputed it and said I can prove I paid every month. then I was told it was an unneccesary call out fee! I said to the consultant are you sure now? Are you done looking for a reason why my bill is ********ly inflated? Clearly there is no low enough level for Telkom to stoop to when it comes to customer service, ********l and inflated accounts and non-deliverance
