Worst service ever.

I have been trying to set up a service offered by Telkom. On 20/02/2018 for about 3 hours on phone with their fault logging dept and promised a call back. Needless to say, never got the call. On 21/02 again for ever on the phone with them. 1st person promised a call in 30 min, but 4 hours later no call. I called again and provided ref no given earlier and was informed they do not pick it up. Was assisted by the rudest person ever, not willing to listen and informing fault is on my side as my products is not ****ioning correctly. Did not even want to listen when informing her problem the same is on 2 different devices. When asked to speak to a manager I was informed he will not speak to me??? Where to from here Telkom. Can I cancel my 2 year contract only 2 months in? And then, to top it all, I get a sms saying I dropped the call. Guess they're going to say I dropped all the calls since 20/02.
