EMACHINES

I just received my computer back from it's 2nd stint at gateway to get the motherboard replaced. Imade sure i marked the motherboard in 3 different spots to makesure it is getting replaced it went out friday the 21 of March i got it back today. i opened the case and looked at the motherboard and my 3 marks where still ther and i am still having the same problem . i called tech support they referred me to the Corp office because it would be the 3rd time i would have to send my computer back to get fixed. after the 3rd time your entitled to a replacement computer. I spoke to the Corp office and i was told the motherboard was changed. i explained what i did and Linda one of the corp managers told me " well my screen shows the motherboard has been changed and i have to go by what my screen says". I asked her was she in Tennesee when they changed it? Did she see it? i know what i did and i know that the motherboard was not changed. I requested to speak to someone higher than her . she said there is no one higher than her. I filed a complaint with the BBB. I had the computer since the end of Feb 2008 and already it's been back 2x to get repaired the last time i had it for only 2 days.Tech support for thst company is braindead and rude.
