[Resolved]  Samsung — Samsung Galaxy Tab 2 motherboard failure

I have purchased the Samsung galaxy tab 2 device back in July 2012. In Mac 2013 the device could not power up. I sent it for repair at the Authorized Samsung dealer in Gardens Midvalley. They say the motherboard has failed and got it repaired/changed. After a few month now in August 2013, the same issue happened where I can't start up the device. Sent it again for repair in the same center and they sat the motherboard again has failed. This time I'm no longer covered by the warranty since it ended 1 month ago. They told me it s gonna host me me 550 to get it fixed. I'm not willing to pay and called Samsung service center to lodge a complain on the quality of their product. They told me the motherboard condition could be caused by the usage. This is totally unacceptable to me. How can s device motherboard fail due to internet browsing??? They told me they can 'try' to apply for a discount for me to fix the issue but there a no avenue for me to lodge any complain. I'm totally dissatisfied with the quality of the Samsung product and how they re not willing to take full responsibility for their product defect.
