Please bear with me as I will explain in more details below!
Most financial platforms will store your account if it is removed. But nothing can happen.
It is important that you have not closed your account for more than a month. There is a high probability that the account cash is permanently removed from the app system.
I myself tried to open my account, which I closed 3 days ago 'and I was able to contact the support team, and then my account was reinstated.
So this is what I would suggest to you. Hopefully, you can get your account back.
