Fraud from loan facilitation websites for retirees

I received a phone call with explanations and was asked to send a photo of my ID and family book, and to send an amount of 20 dinars to a bank account to complete the loan procedures, which amount to 5000 dinars. I was told I would receive the money the next day through a representative sent to sign the transaction procedures and receive the amount. The credibility of the site was confirmed to me by comments praising the company's credibility and the speed of procedures. However, when I contacted the bank to which I transferred the money, they confirmed that it was a scam and advised me not to send any amount to the account. The bank took the necessary action by freezing the account. I provided them with the numbers and the name of the site on Facebook and reported it to the cybercrime department with full information, but I have not received any response from them until now. The incident happened about 10 days ago. This is my story.
