Charged installation for line that wan't installed

I asked for my line to be transferred to a new premises. Telkom was unable to do so so I tried to cancel my account. The next month I see on my bill that I was charges for installation of a phone line.<br> <br> No line was ever installed. So I asked why I was charged. I was told to log a dispute. <br> I explained the situation. and it was logged. <br> <br> On my next bill I see the amount is still there. when I log in online it says that the dispute was rejected. <br> <br> I want this account to be cancelled. and the amount refunded, <br> Cant get through to call centre.
