Somebody stole my whole club

Someone stole everything from me. I received an unusual activity alert on my email account, and I immediately logged in and reset my password. When I logged into the game in the evening, I saw that the 1M coins, 4000 points, and all my tradable players in my squad had been sold and stolen . I changed my passwords, but everything is gone. Please help. My entire monthly intern salary has been wasted.
