FNB incompetence and unwillingness to help

This is desperate attempt to get FNB's attention. Yesterday (8 July 2021) FNB deleted my online banking profile because according to FNB it was *******. So they deleted it, this means I now have to register again for online banking so that I can access my banking online AND download the app. This I cannot do because I am in LONDON and in order to register and finalise my online banking I must visit a FNB branch or FNB ATM. This is not possible and when I called the international number for FNB they said they cannot help me. This is ridiculous, I now have a fnb account that I cannot use and because I cant use it I am in major trouble here in the UK and cannot pay rent. On the phone you guys are also useless and I failed my authentication because I could not tell you my postcode number. FNB, you better call me in the uk +***04 or email me *** or I will close every single account with you
