Charged for already Having a line installed.

<p>A few years ago we had a ADSL line installed and obviously paid for that installation( cost R605) our line was disabled but now it is enabled again. When I look at the statement for this month it says I was charged installation fees of 605?? But I explained to them well before they connected me at the exchange that I already have a line installed, will I be charged again and they said no every time I called and asked. I am unhappy with the service Telkom has given me since I activated my line again. I received three sms that said someone will come and connect the line and no one came each time and no communication was sent to me but now I must pay an installation price for something I already had? Sort this out. </p>
