I have purchased one karbon a40 mobile on 07th nov. 2018 from poorvika mobiles pvt. Ltd., ambattur, chennai
Since its purchase i am unable to use the mobile, often while attending the calls it is getting disconnected and karbon screen appears and i have to restart the mobile. Sent to authorised service centre twice but still the problem persists. Dealer wants letter from service centre for replacement. Please instruct the service centre for replacement. Kindly do the needful. Regards.
