WHERE IS MY MONEY NEDBANK

Am very frustrated on the way Nedbank is handling my business account. They were 3 cheques that were deposited on my account on the 8th of July 2020 at Dobsonville branch and 1 at Westgate branch on the 14th of July 2020. All these cheques are not reflecting in my account. Am being told by the Branch Managers that they do not know the contact numbers of their cheque processing department and then can only communicate with them via emails. This is very shocking to me, if i can get that response from Nedbank.

PLEASE NEDBANK I NEED MY MONEY. THEM I CAN MOVE TO OTHER BANKS THAT WANT TO THREAT THEIR CUSTOMERS FAIR AND WITH RESPECT. AND IN TIMES LIKE THESE SURELY CAN THEY DO THIS TO ME?????
