I SHOULD HAVE CAME TO HELLOPETER B4 BUYING ACER

i really should have came to HelloPeter before buying an Acer Laptop. i sent my Acer for repair on my charger socket and before i sent it my screen was working , i made backups and they sent me a quote , we agreed on the quote and last Friday they sent me my laptop back and the screen does not work. i call call center and ask them don't they test their stuff before they sent it back ? out of ignorance he said they tested my laptop. Took the laptop and added an external screen, i see its working, but the laptop screen is not working. 2 months after i bought this laptop i brought it back for screen problems and they said it was the back light, how can i have 100 problems with a Laptop i bought with such large amount money? now i ask this agent who will pay for courier if this is your fault, he says me. wow here comes ignorance again. i have learned the hard way , Acer is not a good Brand no way. i can't believe this, it's not possible no no no no.My Previous Case number ***S
