Regenersis (India) Pvt Ltd — improper service

Address:

Pune, Maharashtra

On 16 august i visited your service center for repairing my handset one plus 3, which was facing low ear piece volume.
This problem was solved by your men but after that my camera and flash stopped working which were perfectly working before giving it in service center.
Every time when i visit your center due to these kind of reasons i have to visit them again.
I want to register a complaint regarding this.
