Unsuccessful Mandate

Good Day, BIDVEST BANK TEAM. I am typing this review to you out of frustration. This morning I received a mandate that had to be signed, i went into it and entered all my correct details just as I had done last year in April. I receive my payments through Wise as it is international due to my job. I got the mandate telling me it's unsuccessful and I have no way to retry it or recheck it. I have reached out to you guys via email and phone and had no responses yet. I have proof attached as well. Please sort this out asap im awaiting payment.
