Repair overdue and no feedback

Booked in wris****ch on 20 Nov 2014 to replace glass. Was told lead time would be 6-8 weeks. It is now more than 12 weeks. When initially enquired about the long lead time, I was informed that the watch is sent back to Denmark. Follow up in Jan 2015 revealed that the watch was in Johannesburg all the time. The response to numerous follow-ups during Jan and Feb were that the watch is still being repaired. I visited the Tygervalley store 2 weeks ago and was told that the watch has been repaired, but there has been a misunderstanding and the Repair centre requires payment before releasing the watch. Edgars states they never received the invoice and would sort out immediately. I was told to come back last week Monday. I went to the store on Thursday and was told the exact same thing. I called the store and requested the manager to sort out ASAP and provide me with an ETA and requested that I not have to pay for the repair due to this bad service. I have not received any reply.
