poor professionalism

im a car dealer i paid one of my supplier in Sasfin bank and they blocked her account the requested documents from me i send them but still the account remains closed, now they want the proof of payment from capitec business account we provided them with it unfortunately the account remain closed, what kind of bank is this that don't know the difference between capitec business and savings account are not the same even their proof of payments are not the same instead of calling the person who paid or her banker they dont but they know how to close other peoples account i will never recommend this bank to anyone because of they professionalism, even now it still remain closed
