Nedbank sending me from pillar to post

I have recently relocated , and am trying to close my Nedbank savings account, which is proving to be impossible. I called the branch, they tell me I must go into my nearest branch to close it (impossible as I'm not in the country). Then they tell me to call Customer Care. I then call Customer Care, and they tell me to call the branch.

Please can someone assist me - I'm incurring fees on this dormant account and want it closed. It's 2019 - you can't tell me the only way to authenticate me is by seeing me in person.

I've provided my details under 'additional information'.
