Unreliable and still no phone

Took my phone in for repairs on the 13th of August in the late afternoon. I was given a lead time of 10 - 14 days. On the 17th of August their updates advised that parts had been ordered meaning the lead time would start from then. Well the lead time has come and gone. No updates since I raised a email escalation on the 27th. It seems the only way to get updates is to keep emailing. I'm still without a phone. I wouldn't recommend them at all. A phone is such a sensitive thing. One would think in this service industry they would understand that, anyway let's see how many months go by
