Telkom trying to ***** from loyal customers

I have been a loyal and happy customer of Telkom for sometime now but recently I upgraded from a 4mb line to 10mb. I was assured this a free change over no costs involved except my premium will be R799. Upgrade was done then I inquired about my lit box I should receive they ensured me this is on its way. A few days later courier co came and delivered a router???? Why would they do this if I already received a router for my first 4mb line contract?? I called Telkom and told them I received a router and not lit box and they said the consultant incorrectly processed this. Anyway I ended collecting Lit box in Stellenbosch and also advising Larna Wellman that I had received a router that I know was not due to me. She said it was my luck. Anyway to get to the point I have been charged R3600 this month for a router and cancelation fee which I was assured is a free upgrade but I am being charged penalties. Please go and listen to my recordings. I don't appreciate Telkom trying to ***** from their clients. This is not the first this happens they tried to bill me for a FREE wifi extender when I first took out my 4mb line contract.
