Telkom charging an exorbitant service fee that I was never told about

I received my bill yesterday and to my suprise I'm being charged a service fee of R798.95!!! This is such an exorbitant fee and not once during the sales call/placing of the order was it ever mentioned that I would be charged a service fee of R798.95 or any service fee at all. This is just ridiculous to charge me for something that was never mentioned to me at all during the call/placing of the order. I took the home uncapped 4mbps with Telkom in May after having cancelled my ADSL with another ISP at the end of April. I had called the sales number 10213 and was put through to a sales agent. I informed the agent that I would like to take the Home uncapped 4mbps package from Telkom and the agent told me that the package cost is R605 per month and for the first month I would be charged pro rata. She also informed me that it would take 7-14 working days to activate the adsl. I had an exisitng line with everything already set up and no one came to install anything at my house. I just had to call and get my username and password which I setup on the modem myself. I would like the recording of the order to be listened to.
