Samsung A7 screen not working after 8 days

I upgraded my phone on the 21.12.2015 and have been very happy with the performance of the new Samsung A7. Unfortunately it started giving problems with unlocking the screen on day 5. Thinking that it was just a setting problem on the phone I waited till we got back to Gauteng to visit my local Vodacom store to advise me as to the correct settings. I visited them today and they advised me that I had missed the deadline for replacing my phone by 1 day and that I now had to book my phone in and wait for a quote on the repair of the phone. This could take up to 3 weeks.<br> <br> I stayed with Vodacom with my upgrade as I expect better service from them. It turns out that they are just as pathetic in understanding customer issues. I cannot be without a phone for the next 3 weeks while they try and figure out what is wrong with mine.
