My acquaintance stated to the financial institution that he didn't take the loan and asked them to look into the situation. He left an application with the security service of this organization, and they advised him to go to the police. The same day he went to the branch, wrote a statement describing the situation from the beginning and received a written confirmation about it - he was advised to attach it to a letter and send it to the organization where the loan was taken.
Since then there has been no word from the police on the progress of his application, but he doesn't expect to, he just needed confirmation of his fraud claim.
But when he started to deal with the second loan of $320, he found out that in addition to that some 15 other microloans in the amount from $35 to $125 were trying to be drawn on him, but these applications were rejected. The second loan turned out to be drawn in Novosibirsk, I called them and went through all the same steps, sending them a receipt from the police.
In the end I got a call from both companies, saying that they had established the fact of fraud, apologized and told me that they were removing all my debts and would send information about it to the Bureau of Credit Histories so that my credit history could be corrected. As I understood, this is quite a common practice, and the MFIs resolved this situation on their own within a week of my application.
