S6 Edge - Faulty!!

I started experiencing signal issues with my S6 (4 months old) on 09/09, could not access internet, cant make or receive calls. Finally took the phone to Samsung Head Quarters on 14/09 to be assessed. I booked it in and was assured I would be updated. Zero feedback from Samsung until I eventually got hold of the representative on 21/09. The feedback was there is a fault with the phone and they will replace the phone. Since 21/09 I have been informed that a new phone has been partially approved but waiting for the second approval from higher up. Christine Latchmiah has really tried very hard to resolve the matter and to give me some sort of feedback but it would appear her hands are also tied. The service is absolutely terrible and the response time to the issue with their current flag ship phone is horrifying. If I don't keep asking questions I don't get answers and the answers are always just the same \no news"... Really not impressed with the brand and seriously disappointed. """
