Account blocked for security reasons: URGENT!!


So I have been using Revolut for a short while, topping up from only one card, got everything verified.

I use Revolut mainly to transfer money abroad for my uncle. He has cancer and lives in Bangladesh, so occasionally i send money to cover some of his medical bills.

Everything was going fine until recently I sent through £750. My uncle had let me know that he still didn’t receive the money in his account and was unable to receive the treatment due to this. When checking my account I was shocked to see “Your account has been blocked for security reasons”.

I tried contacting the support services in the app but got no reply. What happened to my money? Why has my account been blocked? How can i fix this? HELP!
