Just relax and stay calm. It's so easy to make false accusations nowadays.
Said by a user that woke up just to apply for a loan and received merits at the same time from same account that recently woke up.
Clearly your account is compromised either sold to you or just hacked. Proving ownership to this account still shady due to the recent behavior towards merit abuse and potential loan scam. Theres a chance that the account is sold with private key so dealing with this user is extremely dangerous.
