6 weeks of poor service

I have been reporting my faulty ADSL line since 3 March (I have at least 5 fault references for this).<br> I have been advised to purchase a new router, which I have done, and still have the same results.<br> I have down graded my line upon recommendation, from 10 meg to 4 meg in order to make the line more stable.<br> This has had no effect, still have the same issues. I keep getting told that the problem is now repaired, but the service is on and off all the time and totally unreliable. <br> I have even tried the Telkom LTE contract service after been assured that I have coverage in our area, but had to return the equipment and cancel the contract because I do not get a signal.<br> I am now desperate, as I do a lot of work from home, and have been resorting to my 3g data to get by, but this is becoming very expensive and slow. <br> I am beginning to think that this problem is beyond the ability of the Telkom technicians, or that Telkom is falling apart like Eskom etc.
