Worst experience from Nedbank

Worst experience I've ever received from a bank. After various emails and calls, my problem has still not been resolved. I have problems accessing my cellphone OTP(One Time Pin) from overseas. After contacting the bank, they send me the instructions on what to do. It's been a month since this process has started and still no resolution from Nedbank. I had to courier documents, do a video call and the final stage according to Nedbank was the verify the info from the video call, it's been a week and Nedbank Management Team is still verifying this video footage. Worse experience ever from a Bank. I asked them various times what more do they need from me, unfortunately, no response. I'm left without accessing my funds from overseas and still no resolution from Nedbank.
