Poor and non existent service

We phoned the call centre to move our telephone/adsl line from Eastern Cape to Somerset West, Western Cape, we explained that we needed it urgently as we use the internet to earn a living, it will take 14 days, probably sooner they said..... To cut a long story short, we received our line in the 2 week of February 2017, apparently the delay was the fact that Telkom's new system doesn't interface with the old system. One problem sorted, next problem, Telkom was still billing our old number, which was cancelled 30 November 2016 and the new number had no data package attached to it, the data was being billed to our old number! This problem can't be resolved because the old account is in arears and until that is resolved nothing can be added to the new number. Have spent the whole of last year trying to resolve this problem, have emailed the escalation centre every day but no one responds! So far it has taken 15months! Really poor, poor service! It is extremely frustrating, if I had to run a business this way, I would be out of business!
