[Resolved]  Homeshop18 — faulty product

Dear All,
I had purchased a product, ZEN ultratab A100 from Home shop 18 in January 2013. The prod id is ZEN[protected] and S.no is MS[protected].
After using the product for couple of days it had stopped functioning. The screen goes blank. I called up the representative of Home shop18 and lodged the complaint. I have asked them to change the product and then some senior official had given me a call and told me to give the product to the ZEN service center and told me that the product will be fine and useable after service. The service center is 40 kms from my home town but I had no option and had to go there.
After few days it had again stopped functioning and got hanged. Again 2nd time I went to the service center.
The third time after using it for a week it had again stopped functioning and I had follow the same process.
It had again stopped functioning for the fourth time after few days and I had again went for repairing.
The fifth time I had to wait for a month as the service center was closed and after a month the new service center opened and I went there .
After using it for 15 days it is again useless and the product is hanged.
During these entire period of time i had regularly called the customer care of ZEN and got the numbers of service incharge Mr Shibsankar Das, contact no [protected] and Mr Prabhat Kumar, contact no [protected] . The service provided by Mr Shibsankar is inefficient as he had regularly asked me to give the product to service center and then he will look into the matter. I had follow his instructions and the result was same as earlier and even now he in not showing any interest to receive the calls or give any feedback.
The amount of travelling exp i have incurred during the entire process is half of the cost of the tablet as you are aware of the fuel price and the time lost during the process.
For further clarification you can contact the previous service ( Mukul, [protected]) center to know the problem i had faced. During the 7 months of purchase, the product was lying in the service center for more then three months.
I need the permanent solution for this or else i have to take the necessary action . Kindly replace the product or refund the money.
I am waiting for the feedback on urgent basis.

Regards,
Gagan
