No access to my funds for two months

Nedbank Home Loans offered me a "Main-banked" offer with a better interest rate on my bond, provided I open an account with Nedbank and move my funds. Every single step of the process was a pain, and now after two months, I still do not have access to online banking or the Money app. This included visiting a branch for more than 2 hours. The only way I can currently access my funds is through ATM withdrawal. I have written emails, made countless phone calls, been passed from client support manager to client support manager, and while everyone is skilled in saying the right things, there still is no solution. Nedbank has taken up so much of my time, which the better interest rate is definitely not worth it. Moving my funds back to FNB.
