Complaint Nedbank

I have changed to Nedbank and this has been the worst ever, as a new client with premium banking account i have been given the run around due to multiple accounts been open there after my account moved to ***** department and after blocking the entire facility, its been utter frustration to access and transact, Nedbank call centre and digital departments were unable to call me on times and dates and i had to follow up with them continuously with no proper feedback, i have gone into a serious back log with my rentals and accounts due to non payment and now im holding Nedbank responsible due to no communication and unresloved issues with them.I am still unable to access my banking app and transact as this gives me an error msg and is locked.
