Tata Photon Plus — just cannot activate

I got a photon plus usb from an executive at my office. Went home and checked that it cant be activated easily. Customer care have no idea about technical complaints. Somehow managed to raise a complaint in the website. After repeated calls to concerned guys, they came and couldnt do anything about it. They were not ready to change the device for god sake. I would like to know whether the company's aim is to dobroadband business or just selling devices.
