Bharat Petroleum [BPCL] — Issue in transfering to a new address

Address:

Room no 6/802, DB ozone. Miraroad east Mumbai 401107

We have been shifted to mira road east recently, so we went to bharat laxmi gas submitted our 2 cylinders n regulator, they gave us thi paper and asked us to visit dev mogra gas agency miraroad. We went there and the staff told us there is no new regulator available so transfer procedure cannot be done. Now i am stuck, i have submitted old one and now i dont have anything wid me. I wuld like to file a complaint against dev mogra bharat gas agency for not providing me a new regulator and behaving rude wid me. Kindly help me urgently wid this matter or else i will escalate this issue further at higher level
