Telegram Commission Scam Took My Money and Blocked Me After Payment

I am writing about a fraudulent online platform that was introduced to me as a site where I could earn commission by completing internet purchases. I am in Iran and have been using this site for about a year. The person who acted as “customer service” and then blocked me was using the Telegram account @UserServices0***. At the beginning, they claimed that if I completed a number of purchases, I would receive commission. I completed around 20 purchases as they requested. Then they demanded that I make a large “combined purchase” of about 1,500 dollars. Since I did not have that amount, they told me that I had to pay 150 dollars as a “tax” so they could cancel this combined purchase. I did not have this money either and had to borrow it; I paid the 150 dollars in parts from my own pocket. All my payments were made through my Ramzinex cryptocurrency wallet. After taking this money, the person who was communicating with me via Telegram deleted the entire chat history and blocked me. I lost access to them, and I have been left without my money and without any commission or service in return. I request that all the amounts I have deposited to this platform be fully refunded to me. I also ask that this platform and the account @UserServices0*** be investigated as a possible fraud, so that my loss can be compensated and others are not harmed in the same way.
