Nedbank doesn't care

I am SO sorely disappointed and aggravated with my experience with nedbank from day one. Not only has it taken almost 3 weeks for my cards to arrive when I was informed it should take 3 days but ever since I'd opened the account with them my app,internet banking AND mobimoney have all not been working on my profile. Clients have been using mobimoney to pay me since mid last year without any issue for me to withdraw. Since Friday I have not been able to retrieve an OTP.. I'VE SPENT MORE THAN 6 HOURS in the branch trying to resolve the issue and now my procurement and cash flow have been delayed... Are you telling me that with ALL THE IT EXPERTS working under you not one can figure it out? I refused to put the phone down until I was assured it would be resolved yesterday. Nobody has contacted me. They have issued and reissued a temporary pin which still won't log me in to retrieve my OTP. I want to close my account immediately and never want to use their mobimoney again. I can't believe the nightmare I've been through trying to retrieve my own money from you guys. Never again.
