Poor service/ risk provider

So I took a a Telkom sa uncapped line out in 2015 but the line was never working from the time I got it I had to keep calling in and logging for a technician until one day I called the call centre and I get told my 4meg line seems fine, so I started to question the agent as I was paying R1299 for a 10meg uncapped line. She could not explain it to me and after I had taken it up I got a call back to state they will refund me for all the extra money I paid and would cancel the line as I was unhappy.

I got a call from nu debt management today to state I still have a outstanding amount of R1500 due to Telkom SA and I have been handled over for administration.

Firstly where was Telkom ethics to call me and let me know about this and for what am I paying that amount when there was a error on there side????

This is the service level we deal with and that is why people are complaining about telkom. Seems like Telkom has found a way to get money out of people by handing them over for an account that was not even my fault.
