Christian Medical College — Not received the Consolidated receipt yet

I had paid the fees to generate the consolidated receipt on 23=nov, 2020. I am calling the concerned desk from 27-Nov. Every time i call, the only reply i get is it is not yet signed and the authority who has to sign is not available.
It has been 10 days now. I do not understand the difficulty here as to how long it takes to get the consolidated receipt printed and signed.
This we need for the re-imbursement process in ECS (Army hospital). WE have certain timelines for this process and I feel the answer I get is highly irresponsible. TEN days for this receipt to get ready is not convincing. Requesting for speeding up the process
