I had booked a bsnl penta is701r bearing booking number pent00136327. I received the tablet on 7-7-2012 but when I tried to switch it on, it was unable to start and when it started, it was unable to load its operating system and its touch was not responding. Also its battery is very very poor. When I tried to call the pental customer care, there is no response from them. Please tell them to refund my entire amount as I feel very uncomfortable with this tablet, totally wastage of time and money. Please make a justice to me.
