Sony Vaio Laptop — Vaio laptop not repaired

Address:

Mumbai City, Maharashtra

I had given my sony vaio laptop for fixing a problem[many keys on keyboard not working]. It was given to metal tech [sony authorized service center] in andheri west mumbai. They have had it since 20 / 07 / 2015 and have not fixed the problem and keep saying parts have not arrived, they are not giving any date for delivery always saying it will take four more days, every time i ask. . Today and i went there and got back my laptop without any repair being done. They made me pay an amount of rs 6000 just to take back my laptop in the same condition that i gave it. They said since the part was ordered i have to pay. Kindly look into this urgently.
