Karbonn Mobiles — usb port track failed in warrenty

Address:

Coimbatore, Tamil Nadu

Dear Sir, I have purchased Karbon mobile model A99 (IMEI no:[protected]) in poorvika mobiles at Coimbatore on 5.4.14 bill no 0261. So for 3 times the mobile charging pin failed and karbon service center in Coimbatore repaired once through chargable basis and twice on foc. now the USB port in A99 is not working which is required upload or download data with my laptop.upon checking with Poorvika and Karbon service centre they say that the track for USB port has failed hence repairing it will cost around 2, 000. My mobile is still under warranty and it was thrice repaired by Karbon trained service centers within this period. Hence i feel the failure might have caused either due to design fault or manufacturing fault or workmanship fault.For your information i also use HTC mobile for last 2 years without any problems, hence do not tell us failed due to handling etc. Hence I request you to arrange to replace my mobile immediately as it is still under warranty. We will appreciate your quick action and reply on this request.
