scams in the Ubii app

Good afternoon, I am writing to you through the app Sres Ubii. I was scammed. I have been chasing them for 3 months to solve a problem I have with my personal data in their app. I am blocked by them, and the worst part is that I have money in that account. I went to the bank, which they possibly have an account with, the Venezuelan Credit Bank, and they do not take responsibility.
