Dear team, I have purchased a Karbonn Titanium S1 phone on 18/09/2013. Within few days it started malfunctioning.Battery was worked properly only for 4 months. But I was not in condition to give it for servicing.And when it completed 6 months, they have denied to accept the battery, as battery warranty is for 6 months only. Post that I was facing issue with touch-pad. For which, phone was with service centre for more than 2 months. Now again I am facing multiple issues & given it to service centre on 25/07/2014. Its more than two months, till the date, phone is with service centre only. Few days back, I got update that phone is ready. when I asked whether they have confirmed the phone is working fine or not, they are not sure & asking more time. Warranty is over when phone is with service centre. In the last 1 year, about 5-6 months, it was with service centre only. Even when I asked for extended warranty or refund,they are not accepting.They are also not sharing escalation m
