Indraprastha Gas Limited [IGL] — Allotment of connection

Sir, I have applied for PNG connection for almost two months back. Which can be assessed by my BP No. [protected]. However, connection has not been alloted despite submission of documents. I have called up customer care every day and DMA alternate day. DMA says documents have been uploaded, whereas IGL says, no documents uploaded. Both advise me to talk to other party. Customer care says talk to DMA. DMA says talk to customer care. I do not know what to do. Thanks.
