Nedbank customer care nightmare

I'm currently overseas & I called Nedbank to enquire on reactivating my business account & I was informed that I simply need to make a payment on the outstanding balance which about R80 . So based on that information I've sent fund's to SA & the branch where I opened the account informed that I have to physically go into the branch. Which is not possible as I am overseas. I've also asked as to how I can get my a one time pin for online banking so I can transfer from the business account into the credit card inorder to settle it. I can't seem to get a straight answer. When I called I was transferred to the"Global department"??? And no one answered. Calling from overseas is expensive especially when you're misinformed on the calls you've made ? What happens to the payment I made ? Can a OTP not be sent to an email address? Can I not reactivate my account with the payment I've made ?
