worst experience ever!

I bought this model from Lowes last week and when I installed it one of the screw holes on top stripped out. I thought this could have been a one time simple manufacturing mistake and took it back to the store. they didn't have another one in stock so I had to drive 50 miles to get a replacement. while installing the new one the SAME SCREW HOLE STRIPPED OUT! I called Frigidaire (now Electrolux) and was told all I can do is take it back for a refund or my money back. I asked several times if they knew of this defect and never got an answer. I also asked what they are going to do for me because of my time and gas wasted and was pretty much told too bad since they can only do what the warranty says. I will never buy Frigidaire Electrolux again!
