Consumer Redressal

I had bought the I Berry Nuclea X handset bill dated 26/05/2014 online through E Bay. I was facing the problem in this handset till the date I purchased it. I submitted my handset at their Ludhiana Service station for repair and it was sent to their Chennai office, I send it on 1st August and received it back on the first week of October and they told me that they have replaced the motherboard but still I am facing the same problems and yesterday I visited the Ambala Service Station and they told me to send it to Delhi or Chennai, I am worried that again they will take more than two months and there is no guarantee that problem will be resolved and in the coming time, My warranty period will expire. Kindly ask them to either replace my handset or refund the cost price of the Handset. The details of handset are in bill attached herewith.
