ONCE AGAIN I COMPLAIN!

I am currently "stuck" out of the country; I have been paying a beneficiary monthly since I have been here (December 2019) - no problem; However, I recently tried to pay a beneficiary who has been on my list of beneficiaries for about a decade, and I can't - because suddenly an OTP/SMS requirements pops up! I did not arrange international roaming on my cell, so, clearly, the payment was unsuccessful. why the sudden change?? I accept that should I wish to pay an arbitrary individual/company on a once-off basis, an sms is required, but I have NEVER had an sms/OTP requirement when paying a beneficiary. the advice I got from Nedbank varies - one person insisting that an OTP has always been required, another saying I must download the Money App (this after I had explained the cellphone problem). Surely there shouldn't be such radical changes when the entire Globe is in chaos!!!!! When I get back this account will be closed - I am done; earlier this year I phoned the call centre from here, the call took such a long time being transferred from person to person that I ran out of airtime; the one person I did get to speak to gave me his email address - I sent him an email and am still waiting for his reply! (this was in about March!) I AM DONE!!!! Oh - and please Nedbank, if you do happen to bother to reply to these reviews, don't bother. I am most concerned as the lady I have been paying on a monthly basis for helping me once a week with housework will be in dire straits if I can't pay her.
