No one is here from Microsoft. Take your phone back for repair or open a proper support case through the correct channels.
I'm sorry but this thread is getting stupid and off topic now... whinging on here and threatening to now buy a MS phone anymore will not help or hurt anyone but yourself.
I am running windows 10 now on my Lumia 930. its awesome! plenty of issue still, but its not finished yet.
Windows 10 Mobile is going to make a comeback. You would only do yourself harm by going and buying an Android or iPhone. they have their place but if you really do love Windows Mobile, then stick to it and just fix the problem.
