I bought a refurbished Acer A500 tablet in December 2012 at best buy of Yonkers, ny. About two or three months later it started to act strange. It would turn off on its own and then it stopped turning on. And when it does turn on it freezes on the lock screen. I am aware that it is out of warranty and you do not offer support. But I have tried answers by Acer and they said that they can't help me if my tablet doesn't turn on. They told me to contact Acer but I can't even get a customer service agent to take my phone call. I have tried to take it to other technicians including best buy geek squad and no one can figure out what's wrong with it and they all told me to contact Acer and that they should repair it if it is a defective product even if it is out of warranty. I now understand why the previous owner returned it. I would really appreciate it if someone can contact me with help. I have been trying to get it fixed for almost a year already and haven't been able to. It is frustrating to have spent $350.00 usd on something I was not even able to use for a long time. so I am asking PLEASE help me.
