Bad Service!

I originally signed up with Telkom for a 10mbps uncapped ADSL package. A few months later Fibre became available in my area and I was contacted via telephone by Telkom asking me to upgrade to 20mbps Vumatel Fibre Uncapped for the same price as the ADSL and that it would not cost me a cent to upgrade. I kept asking the consultant are you sure it wont cost me a thing. She confirmed that it wouldn't. I agreed and Vumatel came a few weeks later and installed. Telkom sent me the ADSL Router and everything was fine, I now had Fibre. A few months on I receive my Telkom account with an Extra R999 for a router device. I call the call centre and they advise me that I owe them this money. I said no I don't because I was told that when I upgraded It wouldn't cost me a single cent. She said, Fibre? Hold on....checked, returned and apologised saying that Telkom had not cancelled the ADSL package and that she will rectify the situation and that I do not owe them anything. Now at this point I'm satisfied. A few months on I get a call from a debt recovery company saying I owe Telkom money! No Telkom I paid on time every Month for my Fibre service for a YEAR!!!! They have put a bad tick on my name at the ITC and "Suspended" the ADSL line that I havent even used since THEY gave me Fibre!!! Called the Call centre today and they cant pick up my Fibre service? I am Highly disappointed and won't rest until they reverse everything they have done.
