Address:

Bijnor, Uttar Pradesh, 246737

I m very disappointed by the karbonn customer care. I purchased karbonn mobile last year 28/08/15 & in this mobile voice problem since december. I purchased from vijayasales indirapuram. Please solve my problem. My contact no is [protected]. I repaired two times in vaishali service center but mobile as it is after few hours or after one day. I really very sad from this mobile. Please replace it.
