My account got hacked to make fraudulent returns

Just posting as a warning I guess or to see if this is happening to anyone else. Not sure how they got my password and my account is really small and private, I’ve only made two purchases on tik tok shop, one made a month ago and the other I already returned. I haven’t been able to access my account for a week and tik tok has been beyond useless and closed my support ticket with no response from them. The only thing I can do now is deactivate my debit card and get a new one and hope my banking info isn’t on there as well.
