Hey guys, so we had a customer in a few weeks ago, his screen was clearly damaged and the guy admitted to taking apart the screen to look at it, because he didn't want to spend much we offered a screen replacement at £70, i think the screen cost us something like £58 its a 14.1, anyway the guy came back two days later saying the screen wasn't working, turns out it was the motherboard that was at fault, i didn't speak to him at this point one of my business partners did and he offered a free motherboard repair because he said the man was raging on the phone, anyway we sent the motherboard away for repair and it came back unrepairable, so i phone the guy today and told him and said id have to give him a refund, he was gave me the usual, you guys clearly didn't test it after you fixed it and you broke it, after explaining to him we have our own chargers here and we did test it and that it was working fine when we gave him it back, i told him our only option is that we remove the new screen and refund him, he was somehow under the impression that the screen only cost us £40 and he wants to keep the screen and have a refund, so after telling him that wasn't happening he took the £70 back and that he wants his old screen put back in and delivered to his house..... we obviously didn't keep his faulty screen so what would you guys do in this situation?
