Acer Aspire 5536 Laptop — screen and display and motherboard

Address:

Tamil Nadu

sir,
I went acer service centre(Address:dotcom,aa-115,shanti colony,anna nagar,chennai-40) primarily for bluetooth issues and speaker problems. They solve the speaker problems but bluetooth remain unsolved.I visited the service centre again,they solved bluetooth issues and created altogether new issues in my laptop,i.e, screen and displays problem.For that i goes again to the same service centre and they did something,taking long duration of delivering.Within an hour o[censored]sing my laptop the same problem persists.Again, i went there, they told the motherboard need to be replaced. And the reason of being facing the problem of screen and display is nothing but the motherboard!!.,that need to be replaced.For the same reason, i went there for four times with complaint numbers:56396,51635,41980 and 7999.AND the same problem came again and again!!...Moreover, the service people have taken a month time or more to solve an issue. They are very late to solve the issues and deliver on time!.
My laptop is still in service centre,they are not replying anything!! When I call them they used to say, I will call CROMA people and all, about mother replacement and will do the requisite service and call back but they won’t!!! Moreover CROMA PEOPLE ARE NOT DOING ANYTHING!!
The service people are not replacing the mother boar,even if my laptop is under warranty, giving excuses that are out of our understanding.

I hope you understand my words and problems and will not enforce me to go for consumer case..
