Funds withheld, No communication, Unimpressed *****!!!

At first everything was going smoothly, on 17 June our last payout was submitted and that was 5 days ago. I then contacted Yoco and asked why the payout was not received and they told us that our account is at risk of ***** and that they are withholding payment until further notice. They told me there is no direct contact number for the risk department and that I must wait for them to get in touch with me. I am still waiting and there has been absolutely NO COMMUNICATION or INDICATION of why this is happening. Our client who paid us has no idea that this has happened and YOCO has not said a word. You would at least expect them to have notified us and given is a timeframe or offer to refund to the client - yet they still took ANOTHER CLIENT PAYMENT after this even though the account is at risk. I am highly disappointed with the service from Yoco and it has thrown my business in the deep end! To date, I await a simple response from Yoco. Highly highly disappointed. It is absolutely ABSURD that they operate this way.
