GMAT exam urgent help

Hello guys. 

I already thought a lot before writing this post, but I really have no other choice, as I tried everything else!

I am from Egypt and the economic situation here is a disaster. 

I already applied for HEC Paris and they are asking if I can enhance my GMAT score, but I can't pay for the exam fees, as there is no card or visa works here anymore and even if I have millions of Egyptian Pounds I can't make the payments as the government is going bankrupt and they are not allowing the money to get out of the country.

I am so down and depressed and I lost my job a month ago due to the economic situation and I can't find another job and the only option I have is just getting out of Egypt.

I am wondering if there is anyone might be able to help me pay for the exam as the last option would be on May, 2nd and I am going to pay them back asap.
