Bharat Sanchar Nigam [BSNL] — ftth-landline connection with internet

Address:

689101

I have taken a landline bsnl ftth connection[protected] for my house, which was installed on 28th august. Now i understand that the ups given to me is without the battery which means the so-called ups is only an adapter for the modem, not ups. This is reported to the concerned engineer in bsnl, but he said that he cann't help it, as the equipment is coming without battery.
This means that it is a cheating case and i need this battery as soon as possible to use the telephone even when electricity is cut.
For your information i have paid rs 1690/- (1199 plan+500 deposit) plus 1237/- during the first month itself. So i am waiting for a solution; otherwise i have to report to consumer protection authority
