Nedbank has lost their soul

I will like to cancel my merchant contract. The only payments I am processing for my guesthouse is funds loaned by my father and not for the business and Nedbank held my last payment for 11 days and then took out R13,551.14 out of a R22,500 transaction to aid my survival with no correspondence or explanation and now I have no funds to pay my staff or conduct business. Thanks Nedbank, you people are a treasure to the nation and a shining example for the banking sector :-( I have been waiting for 2 days to receive a call from a manager but this person is most likely sipping a coffee and having meetings about arranging meetings to discuss meetings and receiving a full salary in this pandemic and really does not have the energy or time to help the clients that actually pay his or her salary. I am aware that I may owe funds for the commission the bank takes for transactions but no one has contacted me regarding this and there has been no communication. Instead nedbank just ***ardly just deducts the funds from the amount transacted without any explanation, discussion or correspondence. Truly breathtaking failure from nedbank and shows there is no soul to the business.
