Marketing company

There was a job advertisement on Facebook. I applied and contacted them via WhatsApp. Then they asked for my Instagram account. I did it and they directed me to a marketing website. The first time, I invested 100 pounds and earned 200. After that, they told me to invest 200. I entered halfway through the tasks, and they told me to send more money. I sent 160 and they let me continue two more steps. Then they asked for 3600, but they turned out to be scammers and I lost my money.
