Installed my telkom package in the wrong house!

They installed my telkom line and internet at the wrong house and have not made any attempt to go and remove my telkom line and internet and to come install it into the right house. It has been four weeks since the order now and two weeks after they installed it in the wrong house. The technician just get irritated with me phoning him the whole time and have not given me one solution or date. of when they are going to come and fix it.
