Cellphone replacement

Returned my son's Sony cellphone on 4 Jan due to the fact that it just switches off by itself. We were informed that we could collect a replacement handset on Friday 8 Jan.<br> Friday 8 Jan we were informed that he was awaiting stock.<br> On Monday 11 Jan informed us that he forgot to order the phone (from waiting for stock to not ordering ????) and that he will have a handset by 12 o clock on Tuesday<br> On Tuesday 12 Jan arriving at the store at 16.00 he is back to the excuse of having no stock.<br> So which is it? Forgot to order a handset or no stock??<br> He will now call once he has the replacement but not sure how is going to do that without taking any contact details from us and my son cant use his sim card in another phone. Guess we will need to visit the store again tomorrow to try and sort this out.
