[Resolved]  Philips, 2.1 Sound System — sound system not working properly

hi,
I had purchased philips 2.1 sound system which has one woofer and two speakers two months before from DASS electronics, Pune, Hadapsar, state maharashtra country India.
within just one week after purchase it got adapter failure problem. Then i called care centre to get it repaired. I got my system after one week and then it was working properly. But now once again my system had same problem as before. Now once again i will have to wait for one week to get repaired. But even after repairing there is no guarrenty that system will work properly. So i have decided that i need my money back.
