Laptop Rescue Laptop Rescue does not have a clue about Mac's Los Angeles California

First this company say's they have fast turn around and expert repair. I send them my Mac Air the first week in Jan. They received it on the 7th and after a month I start bugging them so they give me a Est. of the cost to repair. It's over $300 but I need it back so I go ahead but after many phone call I get it back 2 months later and guess what, its not right. It now does boot up but after a few min. it locks up. I have called and left messages but no return call and no refund. I just dropped it off at Apple and guess what, they charge $280 to fix any Mac Air so I should have done this in the first place. These guys are a joke and I'am not laughing!
