Only deposited but investigated for fraud

17/11/22 I deposited funds so i could start trading but i got an email from the broker advising that all South Africans accounts are under investigation for fraud, couldnt understand why that has to do anything with me as i have not placed even a single trade . They advised that they will release and refund traders upon completion of the investigation by Feb 15th 2023. sent numerous emails following up but still no luck and now ive been locked out of their portal
