Can’t withdraw funds in a regulated broker!! Delay my withdraw for a week. I contacted the broker with varied ways but I haven’t gotten my profit successfully

I deposited twice on November 18 and November 26, $2,398 in total after I opened an account in IMF. I profited $2,538 with over 200 deals.
I applied for withdrawal of $1,500 on December 9, 2020. The web said the withdrawal could arrive in 24 hours but I haven’t gotten the withdrawal yet.
I left a message on the web but they haven’t read it. I called the phone number which is lefet on the web, but the guy who answered the phone said he just helped his friend to register the company with the phone number and he said he would help me contact the staff in the company. But there has been no news till now.
