Billed for a landline that is not even installed yet.

I have relocated over 2 months ago, struggled almost 2 months to get my land line installed at the new address. I have received a bill for for line rental for the month of May when they only came and installed the line near the end of May. I have logged a dispute that the account and bill needs to be rectified already on the 10/05/2018 and was told that it will take 8 days to be fixed. 3 weeks later I phoned Telkom again and asked why the bill has not been rectified yet. They escalated it to the supervisor and again a week later still nothing has been done about my account and I still see on the Telkom site that the issue is still under logged and not even in progress yet. Telkom is the worst service provider I have had and I'm very disappointed in their service. Can someone please resolve this bill issue of mine? My ref. no for this issue is ********** 0.
