Consumer Redressal

Hi I had brought Micromax A87 on 12/01/2013 from Univercell Bangalore. It started rebooting by itself after 6 months. I gave it to micromax service center on 22/10/2013 and they asked me to come after 15 days.but now its been almost 2 months they are not responding on it, i had been to service center 5-6 times but they are asking me to come after 15 days each time i have visited the Center. Could you please help me to get back my mobile from them. Service Center Branch : Malleshwaram Service point (sri sai Telecommunications) Job sheet No :S010214-1013-6024447 Regards Sandip
