Binance Dollar purchase scam through facebook and watsapp

I saw videos on their Facebook page and trusted them based on their claims. I then contacted them through WhatsApp to purchase USDT/USD on Binance. Following their instructions, I sent money to their bKash account. After receiving my money, they told me that there was supposedly a problem with my Binance account and that Binance had placed my transaction on hold. They then demanded that I send additional money to their bKash account to “unhold” the transaction. They claimed that after I paid the additional amount, they would release the original amount along with the dollars I was supposed to receive. I believe I was deceived and scammed, as they continued to demand additional money after receiving my initial payment.
