Karbonn Mobiles — Regarding handset repair

Sir, My self Satyendra kumar Verma resident of C/O Mr Gopal Sharma #251 B2 Shiv Colony Bitna road Pinjore Haryana, On dated[protected] i have purchased a mobile Karbonn S9 Titanium from Flipcart .com at Rs 17990.00 I have invest this huge amount on karbonn because my thinking was that why give a huge amount of money to Other country . But u people change my mind never to purchase costly indian goods, In warranty period the volume button not working so i went the service center of Karbonn as Ranvir mobile solution after opening the handset they said that part is not available, Before opening the Set they dont know the availability of Part after they replied to go to another service center, So i went to Gandesh Mobile solutions on 14-09-14 they kept the handset and answered that in 15-20 days part will come, so many reminder to service center they send the hand set to service team of company on 25 nov 14 from 14 sep 2014 to till date 02/02/2015 near about 5 months handset has not returned back .when calling to service customer care they only sorrow and same answer from last 20 days. My question to u people is only that after investing 18000 rs is it possible to purchase another mobile in mean time when you people are repairing the handset this was last lesson which i learned through this company Satyendra Verma Mob.
