Spice Mobiles — Poor Service with huge long delay in warrenty service .Refuse to extend warrenty period

Hi, I am Dillip, a good spice mobiles consumer . Am using Spice -M-525i vide Mobile IMEI No- [protected] & S IMEI No- [protected] smart phone series handset since around 10 month . Few couple of days back, my handset keep on my desk, after had seen screen is lock and no display in the screen .Even if also am trying take back-up of important contacts and contents but fail to take . So I visited local service centre at Sai Complex, Berhampur, Ganjam, Odisha on 30th October 2014 and get confirmed by engineer that my Handset has Display problem which needs to be replace the LCD . And for that they need to send it other state Kolakata, WB for replacement the LCD . After a long couple of days continuous follow-up with team, I received my handset on 3rd December 14 . Again I found faulty with my Handset side volume controller not working after replace my LCD . Earlier it was working . I informed at service center while am receiving my handset, he refuse to check the handset as he was left the service Center . Then am called to your concerned Area Service Manger MR. Pranab Sahu, he suggested received back the handset and keep it for next 15 days at my end . He will informed me once again when new service open in locally, then again visit to service center for my handset repairing . So My kind concern is that company kept my handset for more than one month, but still repair it fully . So it company fault why should not Spice extend my warranty period . Warrenty Extension denied by Area Service Manager . He suggested that after few days am again giving my handset at new service centre, again he will take another one month time to repair my handset. Really How Stupid Service provided by this renowned company to his customers .
