What happened to mixicali.

This user:
а) you were careless by reusing your password and also using the same passwords in multiple services.
b) this password leaked before multiple times and we showed you a service where anyone can purchase all your passwords.
c) among hundreds of thousand of users you were one the very few users who reused leaked passwords and was affected. You admitted that you reused a password from a previously leaked database.
d) our service is not hacked, no data breach happened, no funds were lost. If the app simply allowed hacking the bad actor would have stolen millions of dollars, which never happened.

Below is our post mortem explaining what happened in your case.
