[Resolved]  Asus — Defective not replaced yet

I am a customer who bought the Nexus7 Asus product for the first time with my hardly earned money. Usually after buying the product people feel happy, and i was expecting a lot as i bought an ASUS Nexus but i am sorry to inform you that from the day i have bought the product i am running through the service center. When this product was in warranty i send it twice to the service center. Again the mother board was replaced. It didn't work for even a month with me. After when the product warranty got expired i came up with same problem- the product was dead and I paid Rs. 12, 300/- against RMA No ING 2520536 on 12th March 2015 to get the motherboard replaced, with an assurance that there after there won't be any problem. Again i submitted the product to the service center on 13th April 2015 with the same problem- Dead Product with RMA no- ING2540293, which i received back yesterday afternoon 04-May 2015. After hour an hour at collection point itself i reported that touch is not working, they again fix it back wasting my another hour. Now when i was working at night it got shut with same problem ITS DEAD. again i have to send it to service center at F1 Info Solutions & Service Pvt Ltd. Nehru place. Please replace my product as you see since the day i bought it i am just running after service center. even by paying extra Rs. 12300/- to the some of Rs.30000/- i am standing no where, just getting RMA nos, and wasting my time in dropping and picking the product. Again i received another RMA no- ING 2550100. Since then i am calling customer care, writing mails, nothing has been received apart from receiving the update that the defective product replacement is approved, but will take time. I am just getting harassed by the company as i made a mistake of buying there product. I need the replacement asap. if not possible then please refund my money Rs.30, 000 + Rs.12300/- and as i see the product has been discontinued, they can charge me an extra amount in exchange of other better product, instead of harassing me further.
