Telkom fails as a service provider

For months I have been putting off writing this review because of the little faith I had left in Telkom. The beginning of October 2018 I took up a contract with Telkom changing from my old service provider because of the good deals they had but that was the biggest mistake i ever made. I went to a Telkom branch to do a number change and the consultant that was helping me was extremely rude. Letting that go I then got my 1st invoice and the amount that was there had extra fees on it but I understood as the call centre agent explained that its a data charge plus the object fee. Then on my second invoice I was charged double the amount and when I called I was told about the being systems are offline...For the past 3 months Telkom has been invoicing me double the amount of money agreed on for that contract without even communicating with me. Today I was about a promotion they were running that I was paying for which was supposed to be free...This contract is a frustration and I WILL NEVER RECOMMEND IT TO ANYONE!!! Dont be fooled by their lousy cheap deals because at the end of the day it feels like a monthly ****. I dont even think I will wait for my contract to run out, I am going to pay it off and go back to old service provider. They run their business like the black market, no communication whatsoever but all they know is to take money and provide a really ****py service. Worst contract ever! I am done with this.
