Telkom - Totally dissatisfied customer

I app**** for an ADSL line in Nov 2017 at Telkom Eventually they arrived at my home in Jan 2018 to come and install. On arrival they told me that they cannot install due to a cable fault that they will rectify With numerous follow-ups from my side the fault was rectified at End of April In May 2018 they came to install the ADSL line. We were very glad that this was done now. Our excitement was short lived. At June we received our first account or shall I say accounts Yes you read correct. The open 2 accounts on my name, The first account started from the first time Telkom were at my house (Jan2018), which the ADSL line was not installed. The second account was from May, which was correct. From June onwards I phoned them every month to try and solve this problem of 2 accounts. The correct account they were deducting each month but the incorrect account the just accumulate. In the meanwhile Telkom thought the way to assist me in sorting out this problem, is to give me over for bad debt. So now I am currently blacklisted for an account that is totally Telkom’s fault. I have already logged 7 disputes with Telkom and still the problem is not sorted. Does anyone know how to solve this, except phoning their call center. That I have done numerous times Disgruntled Telkom Customer Hendry Coetzee
