Sony India — negligence of customer service

Address:

Chennai, Tamil Nadu

Hi I had given my mobile for service in accel frontline limited which is authorised Sony service centre. They delivered my mobile without backpannel screws in it and problem wasn't resolved. So I went to another authorised service center they found it that screw was not there. So they are saying we cant give the service. Even after produced job copy off accel frontline . Due to the negligence of Sony service center. They lost the screws and wile receiving it we don't know about those physical missing. as of now accel frontline limited contract is over we are not able to reach them and another service center are also not giving service .
