In business od breaking phones, not fixing them!

<p>I own a Samsung Galaxy S7edge, that had to go in for a screen repair. It had a small crack in to top corner and was otherwise workikng perfectly; it was charging, connecting to other devices, WiFi, pc etc. The phone was picked up via Samsung's ADH Premium service and sent to Cell City for repairs. I was now informed that the motherboard is no longer working which is why 'your phone was not switching on , sir"!!!!!!!!!! BUT my phone was wprking perfectly when it went in? In other words, they replaced the screen on a working phone, broke it in the process and now they claim that it was not working! How ridiculous!! They are giving Samsung a bad name if this is what aftersales service looks like when buying a Samsung. I am forced to warn everyone that I know and all the clients I work with to stay away from Samsung products (for which you pay a premium price) an to avoid using the services of Cell City at all cost. When I phones to get more information regarding the estimated repair cost, I was 'transferred ' to someone who could assist only to have the phone dropped in my ear. Unbelievable!</p>
