Sony India — unprofessional staff

Address:

Shimla, Himachal Pradesh, 171003

We went to this service centre in sanjauli, shimla for the sony laptop and sony phone compatibility issue as it was not detecting the phone in laptop. 290rs were charged and phone was formatted and data is not retrievable from the card itself now. 250rs were charged for changing the window and it did not happen. If the sony service center itself says we are not able to do it where else we should go. No bills were given, i asked for the fault they are not able to tell me that too.
It's just unprofessional staff that sony has kept which is unable to resolve the issues related to sony products only.
Totally unsatisfactory response from sony.
