Extension of deadline for deposit payment

Dear sir/madam,
I am an offer holder from your esteemed University for MSc Finance and Management and in my offer letter it was mentioned that I have to pay a deposit by 31/01/2022 to secure my admission. However due to financial constraints and unforeseen circumstances, I was not able to pay the amount. I am extremely apologetic for the same. I would be extremely grateful if you could extend the deadline by a week so that I can pay the amount and secure my admission. I do not want to lose the opportunity of studying in your reputed University. I hope you look into the matter and do the needful. A positive reply from your end would be highly appreciated.

Did they extend your deadline last year? Or offered you an alternative way/second chance later to pay the amount?
