Telkom internet -- Intermittent disconnection/speed fluctuations

Since 18/12/2018 I`ve had constant and intermittent disconnections and fluctuating connection speeds. I`ve reported it to Telkom on 18/12/2018 (Ref: ********** 0), they reset my port, tested the line and claims everything should be fine. I was connected for a few hours before it started disconnecting and (when connected) dropping speed so low that it wouldnt finish a Speedtest. I wanted to report it again on the evening of 19/12/2018 - but the operator told me they couldn`t check what the issue was (couldn`t connect or something?) and that I must phone back later. The morning of 20/12/2018 the connection was again stable for a few hours and then started disconnecting again - as such I reported it again (Ref: ********** 2). Problem is that my download speed varies between 6mbs and 0.1mbs...sometimes it just drops connection completely. . I pay R722.00 every month for a 10mb line and have been experiencing this issue for four days + now - yet they havent despatched a technician to check the line running the pole to my house - I have to be happy with this slow speed and constant disconnections?? Everytime time (daily) I phone them it takes a 20min call and they still don`t fix it. This is totally unacceptable.
