Consumer Redressal

sir i have purchased a BSNL-Penta Tablet from a shop at thrissur, Kerala. in 5 days time a line appeared on the screen and as discussed with shop i have returned it the service centre on the shop. after continuous follow up with them i got the product replaced after 2 weeks. now it is just about to complete 1 month. now this replaced tablet also has the same issue. when i called the shop they are asking to submit the tablet to the service centre. during last time itself i had gone to their service centre and called them several times to get it replaced. now i have lost confidence with that product. while i purchased the unit i was told this is a very good product and no complaints reported. i have paid Rs. 9,500/- for this. can i get my money back? i am ready to return the product just as i bought including all the accessories and box. please extend your support and advise me what i have to do. Thanks in Advance Shoy Jose 8547178105 / 9567779776
