Bharat Sanchar Nigam [BSNL] — no landline connection provided

Address:

Khordha, Odisha, 751021

I have applied for a landline connection but no work has started.. I still don't have a landline connection since past 5 months.. I spoke to the sdo im bsnl office in bhubaneswar.. He is giving me numbers which only ring but nobody answers since past 5 months.. Now they say that they cannot find the underground wiring so it is not possible to give me a new connection..
I was first approached by an bsnl executive who took money from me at my residence then he vanished for 2months... I found him in the main bsnl head office and got my money back.. Thereafter i again applied for a new landline connection and after 5months now they say nothing can be done...
Please help me.. First the bsnl executive does fraud with me and now the head office is also reluctant to help and i have already paid rs.500 to them.. My customer id is [protected]... The proposed phone number is[protected]..
My address is plot no.383, near dav public school campus 2, sailashree vihar, bhubaneswar-751021. Khorda district..
I have also contacted the customer care and also filed a complain in bsnl website online but nothing seems to be happening...
My complain number is :ors/co/2017/589..
The status is still the same since past 5 months..
