Telkom Poor service, billing incorrectly monthly and not fixing it in over 2 months.

Telkom is literally the worst company to ever deal with. I had taken out a contract with 1gig of data for R220 a month. I then wanted to migrate it to a 2 gig a month package which was R250 and they explained to me a million times that it would be fine and it will not be 1 cent more than R250. When they migrated it, they charged me R2500 for a new device which I never took out. I had to get that sorted out. The 100 minutes that came with the contract was no longer coming through and I made about 10 calls to the call centre and they insisted that the minutes came through. Eventually when I went to the store, they saw they did not load the 100 minutes. When they eventually loaded the 100 minutes which was part of the package, they are now charging me R40 a month for it and no one can resolve it in over 2 months. Uptil this day, I have record of over 10 emails to people at telkom and they send you a sms to say the problem is resolved yet it isnt.
