Business was sold a year ago but the bank account is still not allocated to the new owners.

Our Business was sold almost a year ago to new owners. A binding contract was drawn up by attorneys witch stipulated the new owners has taken over all aspects of the business bank accounts, debit orders included. The new owners went to Fnb Pretoria North numerous times we have called from New Zealand try to sort this out but no one is helping. Since the business account after a year manage by new owners is now heavily in the minus and debit orders start bouncing we just want to ask FNB Pretoria North are you guys maybe looking for us regarding debt just remember we don't have SA contact numbers or addresses anymore now for almost a year or did you perhaps wake up and start to change the bank accounts and debt to the rightfull owners. business email address is ***
