Poor Maintenance Service

I have a 10 meg uncapped internet provided by MWEB, for this to function we need a Telkom ADSL line. We are having all sorts of trouble with getting a decent signal, at best when doing a line test we get 2-4 megs a second. MWEB say that the problem lies with Telkom and have logged a service request with them (20 Feb 2020) and have, after several followuo calls from me, they have escalated this to Telkom management on several instances. I have phoned Telkom and they agree that the line is faulty and will attend to it. This fault i still unattended, what has happened to their service? Right now they must be the worlds worst Telecom provider. I dont know how to sort this mess out!
