Embassy asking for source of funds

[paipvora]

Hi I'm going to persue my master's in uk in coming fall intake. I took loan from Avanse as the Avanse's loan sanction letter is not workable they opened a bank account for me and deposited that amount in Bank account . While document submission I have submitted that statement in VFS. Now I got a mail from embassy asking for the proof of funds that were deposited by Avanse. Does anybody encountered the same issue? Please help me out thanks in advance.
