Sony India — Not repairing my mobile - Sony Xperia Z

Address:

Bangalore, Karnataka

I gave my 'Sony Xperia Z' mobile phone for repair on 24th of March 2015 at Sonnet care, 13th Cross, Cmh Road, Hal 2nd Stage, Indiranagar. I have already paid half of the amount and customer representative told me you will get your phone within 15 days but even after 45 days i do not have any update from them. Every time I called they says parts are not available and it will take another 15 working days. This is really frustrating. This is Pathetic service. I really don't know where and to whom i need to escalate. They have the worst service provider I ever came across. My Job ID - W[protected] Representative name - Sachin Could you please look into this matter as soon as possible?
