Sony India — Delay in mobile servicing - not able to confirm delivery date

Address:

650095

I bought xperia c4 dual in march 2016
Due to display issues, & camera app not responding issue i have given my phone to service center on 29th june 2016.
They said that repair will be done in 4 days.
When i contacted them on 4th july 2016. They were clueless about the status of phone & not able to say exactly when they are going to deliver my handset.
Please resolve the issue as soon as possible
