Finchoice - **** account created in my name

Finchoice allowed an account to be created in my name without my permission. Finchoice somehow obtained by bank account details and deposited 3 amounts (I'm guessing a loan) into it. I also got an sms from Finchoice saying that my phone number has been successfully changed. I called them to tell them that I never opened an account with them and said they would look into it and get back to me. They didn't. A month later Finchoice debited 3 amounts from my bank account. I called Finchoice again. They read me the payslip amount that was submitted under my name and it wasn't my company/salary. They, therefore, inadvertently admitted that they accepted **** payslips in opening an account in my name. I asked them to close the account and they said they can't help me until I get a case number from the police. I went to the police they said they can't give me a case number until I have proof of *****. I don't have proof, because Finchoice refuses to share the ********** payslips with me. Catch22. Still waiting to hear back from Finchoice regarding my concerns after I emailed them the above story. I just want to pay back the remaining loan amount that I never asked for and close the account I never opened.
