Two accounts open when moving homes

I recently moved homes and had telkom install a line only to find out they have installed 2 lines and the one I was making payment to is not the active one. They have no suspended my line and expect me to pay R3000.00 yet i have been paying all this time to the other account which should not have existed in the first place!<br> <br> Calling their call center is a waste of time as i'm told to go to the shop. Going to a shop is waste of time as they tell me to call the call center. Can please someone assist me.
