Destroyed my phone

<p>I had a problem with my A7 charging block. I took it to Samsung smart care repair centre. When I received the phone the motherboard was changed. The phone suddenly started freezing and there was a mark on the camera. upon returning the phone to the smart care centre I met with François, who appeared very helpful . He told me the phone will be assessed and fixed and I can return in one and a half hours to collect. I returned as stated but was told he is on lunch, and then told tht my phone needed parts. After insisting to see him, he comes to explain tht the phone had software issues tht were updated..But the camera must be replaced as there is a burn mark on the camera . Before the phone went in for repairs the camera was fine! so obviously whoever replaced the motherboard damaged the camera. I explained that I am unable to come to the centre again...bt he said he will order the camera, which should take 24 hrs. And will arrange collection. This was on 6 December. A week later, no communication from anyone. I still have my phone which I can't even take a photo on...The phone freezes all the time. And yet when I handed in my phone the phone e was perfectly fine.</p>
