MacBook Air damaged after repair
I sent in my device for repair to an Apple Authorized Retailer after it was acting weird after a software update, when I got the device back, the screen and keyboard were damaged, and the device would no longer charge nor power on. The specialist said if a new problem should arise, ask for a replacement, but due to the device being so old (2012), they said there was nothing that could be done. So now, I have a device that will not work. What do I do, as I don't have the money to buy a new one at full price?
MacBook Air 13″, macOS 10.14
