Pathetic ADSL service from Telkom

I have been having issues with the inconsistent speed of my internet at home for over a week now. I reported the fault via the telkom app and i still have not recieved any feedback what-so-ever. We are paying for a service that we are not even able to fully utilise. This is not the first time i am having these sort of issues. It seems like an ongoing issue which will never get addressed. Im paying for a 20mb line and im getting download speeds in terms of kb's. When will this issue ever get rectified?
