Cancellation Telkom horror

Absolutely horrid experience when cancelling my contract. Started in Feb 2018 only finished in June 2018.

I had paid 30 days in advance related to the cancellation, then received a bill which I queried. Had to redo the entire process.

30min on the phone, and no direct answer as to where my request was? How is this acceptable. Not that this was done almost daily over the period.

The 1st time I submitted an email application recieved an reference number from telkom and then was told they lost it?

How is that my fault, when I'm able to prove I sent it?

Will actively advise people never to use Telkom!
