My name Jit Kundu. Ph. [protected]. Email. jitkundu90.[protected]@gmail.com. phone IMEI NO. [protected] and [protected]. I brought karbonn a 12* from flipkart on 18/08/2014. After two months display problem occurs. I took it to the nearby service centres as given in the service centre book list. But there were no service centres now. The service centre lists are...in hooghly, West Bengal..Joy enterprise..ph-[protected]/ [protected] and Tarama Enterprise...ph.-[protected]. I also go to the Burdwan district.. In West Bengal...Deepak Electronics ph.[protected] / [protected], Mukharjee telecom ph. [protected]/[protected]..But no where the service centre remains. I also go to Raj mobile in Burdwan..ph.[protected]. The Raj mobile said that the phone is not resistered in their computer data, but airtel network charged 3 times, each time three rupee for karbonn mobile registration. The karbonn customer care cut my phone whenever i tried to call them. They totally cheat me. My phone is now useless. Please help me.
