Sir,
I bought "SONY ERICSSION MD400 USB MODEM (Item # 221186159920)" vide PaisaPay ID # 33243460894 on 04-MAR-2013.
The said Modem is not at all working. Windows denied to identify the Device. I tested it in many Computer and in many OS Environments but to no avail. The Modem is still under Warranty. I tried to get in touch with the Seller but eBay Page is showing him as "NOT REGISTERED".
Please guide me what to do.
