Alone In A Foreign Country During LockDown | No Internet Banking, No Responses

I am working abroad in the midst of Lockdown. I have got a new phone and with that a new number. My OTPs however keep on getting redirected to my old number. As a result I have not been able to register mobile banking. Considering I can not get my OTPs and I can not verify payments through my banking app, I can no longer transact at all, whilst being alone in a foreign country. I have spent numerous hours either waiting on calls or on the useless secure chat waiting to have my OTP changed as this is a massive emergency. I have a premier account and would expect some level of personal service but instead I have received nothing. I keep on getting passed on to the next agent. I need access to my banking to survive especially in a foreign country with no one else to cover any of my cost, yet in this time of need, FNB is a complete no show. I am not only incredibly dissapointed but extremely worried at the prospect of not being able to cover my cost of living here because I don't have access to my banking. It's a scary situation.
