It's pretty weird what happened. Could you describe in more detail what device you are using and how someone was able to hack into your account? Did you have a simple password? Is your mail intact? I think that the hacker who got into your account purposefully went to take out a loan. And maybe it could be someone from your environment, someone who knows you.
Have you seen the IP address change?
