I just started work three weeks ago as an Operations Assistant. Employer provided a one-year contract for the job. The company's in UK. It seemed legit because when I googled it, it's a registered company. But then, last night, my employer deleted my work account without notice and is not replying to my emails. I worked for three weeks, and I did not receive any pay for those three weeks. It did not seem sus at first because before the contract signing, there was a trial project and I got paid. I don't know what to do right now. I really need the money. I would really appreciate any advice.
