Telkom disgusting and worst possible service imaginable !!!

I decided to upgrade my ADSL line from 4 MB To 20MB fibre. What a complete and utter disaster. First they cut my ADSL line before my fibre line was up and running for a week. Then my fibre was set to 4MB not 20 MB. They then billed me for the modem, which they admit was incorrect (free modem part of the deal). They say they can't upgrade the line to 20MB because I have been handed over to collections for non payment of the modem. They can only credit me up to 15 days time. Only then can they correct their mistake. Absolutely disgusting service. Also for over a month now I have been calling their call center to have these issues resolved and 90% of the time their systems are down. I have also spent literally days and days, hours and hours holding on for someone that cannot assist. I cannot explain the frustration, and I just have to say to all of you out there, sure go with Telkom if you would like to make your life a complete misery.
