Happened to me a few weeks ago . No explanations at first and bank just told me my company balance. Absolute nightmare,all funds frozen for 4 days. Merseyside fraud squad ended up calling and saying that because I dealt with Dubai we were flagged,also our website had some inaccurate info(dead links as it was getting updated)

My accountant told me to leave it but surely I can at least claim loss of income? I lost a costly contract in that time
