I took mine to the nearest "Authorised" shop because mine wouldn't wirelessly charge. They tested a pad they had at there shop and confirmed the problem (great so far!). This occurred on 14/01, and they said they will send it in and then give me a call when it gets back which they said would typically be five working days. I call up on 22nd and am told that it hasn't come in yet. I call up on the 25th and am told it hasn't come in yet. I call up today (29/01) and it STILL hasn't come in yet, but apparently they will need to just replace it which takes longer(?) so it should come in tomorrow or Thursday (apparently). So presently I have been just over two weeks without my phone but am still paying my contract.
My experience of Nokia "Care Points" (this is what they call them) has been woeful and I eventually logged a complaint with Nokia about the one I visited.
When I went to with my Lumia 920 about the creaking/bending top, the person there told me that he had no idea what was going on as it was a brand new phone (just released he said) and this was only the second one he had seen.
He said he would "find out" from Nokia whether this was a fault and get back to me. After a week of phone calls with promises of updates "tomorrow", I gave up, filed a complaint and dealt with Nokia direct via chat.
As far as I am concerned there is no point whatsoever in dealing with "Care Points", direct support is far superior and able to make things happen.
