Micromax — micromax care center misuse my phone during the service period

Address:

Jorhat, Assam

I bought a micromax A109 phone on 10th Feb 2015 from a shop of Jorhat, Assam.After four months o[censored]sing, it shows some screen and touch pad problem.I went to the shop from which i bought the phone and the shopkeeper advised me to go to the Micromax care center as my phone still has the warranty period.I went to Micromax care center at Tarajan, jorhat, Assam.They asked me to keep my phone at the center for one week.But after 18 days when i called at the micromax center and asked about my phone they told me that my phone was not recovered.so i decided to take my phone back from there because i need my phone urgently.After receiving it from the center on 10th July 2015, when I switched on my phone at home i found that someone misused it.The social sites like whatsapp, facbookmassenger etc were downloaded in the name of some unknown guy.I also found some images, video, games etc in my phone's gallery.Today on 11th July 2015 i went to the micromax center and asking them the service receipt as they kept the reciept with them after giving me the phone on 10th July.But they didn't give it to me.They did not even apologies also.Therefore though i have not the service receipt proof but i have still not inseterd my sim in my phone, hence the unkonown guy's masseges still here in my phone.
