Worst Service!

Worst service! When I got my adsl line at home just over a year ago the promotion stated that the first relocating will be free of charge. 3 months ago I relocated and telkom charged me R615.23 for the technician to came out. After seeing this on my invoice I immediately phoned them and a ticket was logged. This was on the 13th Sept. Today is the 30th Oct and no feedback. After I phoned more than 3 times I was told the ticket was "escalated", even after this, still NO feedback. Why do you charge me for something that should have been free of charge and then don't get back to me once I query it?
