ADSL line down with no commitmemt from telkom

I have reported a fault on a down ADSL line on the 5th of February 2018. Calling about every other day with regard to said fault, the response was that they escalated the fault and would foward it to a the relevat technician who would in turn comunicate the response or due date to me, the client. I have been a client of this company now from 2012 and have never changed my telephone number. Each time I phoned they would give me another number which I have never been the owner of. Apart from that there has been two due dates upon the service should have been fixed by the technician, one on the 22nd of February 2018 and the other on the 15th of March 2018. I have not received any communication via email or sms during this period from telkom, never mind on the dates mentioned above. The issue is that I am still being billed during this period by Telkom although receiving no service or any feedback or commitment date of when this issue will be resolved.
