Maxx Mobile — Gave mobile for service three months back but did not receive yet

Address:

Chennai, Tamil Nadu

I had a problem in touch screen and gave mobile to Maxx trusted service center named 'Chennaii cellular service' in purasaiwalkam high road, Kellys on 2nd December 2014. I'm calling him every week but the only respond i'm getting is "We have sent to service center once we receive we'll call you back". It has been more than three months but the response we get is very annoying. The shop keepers phone number is "[protected]" The bill dealer gave has become old.
