phone in since 9 September

My phone was booked in on 9 September and quoted a 2-6 week repair time. After 6 weeks I was informed they are awaiting spares. I have tried to establish when I can expect spares to arrive and delivery to be complete via the website enquiry form (twice) as well as by calling in to the Branch. The email response I received was that they are awaiting spares and the case is closed. The branch informed me that they had no info aside from awaiting spares (spoke to branch 5 November). I asked them to kindly find out from the repair centre what is going on - it was 8 weeks from date of booking in at this point. I was told they would have to call the repair centre and that they would phone me back. I am still awaiting that call 5 days later. I feel that as a paying customer, there should be better communication. I need my phone desperately, and I would very much appreciate some level of feedback relating to the repair. We are approaching the 9 week mark, and that is an unreasonably long time to retain an item for a simple repair. I am due for an upgrade in the coming few months and honestly don't feel that this is the type of customer service i would like to deal with again in the future.
