Very very very bad technical service

Considering Telkom? I have to warn you that you will not get any help once you are on the network. It seems like they have only sales and accounting departments. I have had issues now for more than two months and stil can't seem to find a person at Telkom that can fix it. I upgraded my 20Gb contract to a 120Gb contract. Everything on my side still says 20Gb and I also only recieve the 20Gb contracts data but I'm charged the 120Gb contract's rates. When I call telkom they say all is correct on their side. When you create a ticket it gets closed with no feedback, It just states issue resolved. I will be spreading this message as wide is I can in an attempt to crippel telkom's new sales. I can also not cancel the contract because the I will be charged for the outstanding term. I'm very frustrated and pretty sure its ******* to charge somebody for something and only give a portion. Please stay away from telkom if you are ever concidering joining them. You can contract me and I can give you all my bad service experiences over the years with them.
