Utterly disgusting service amidst a global pandemic!

I had just the worst experience with FNB over the past couple of months. In a situation where we are experiencing a global pandemic and people have been locked out of their countries FNB has failed to assist me as one of those customers and instead have chosen to send me letters of demand and send my issues to the attorneys. I have had the same recurring issue with FNB since April 2020 over my business account as I have been locked out of the country since Covid lockdowns, I have explained this to them asking them to contact me on the international number I am using, they have not. I have asked if they needed me to get affidavits from the police in the country that I am in to prove where I am, incl my passport etc, no response. I explained that I am a small business owner whose business relies solely on direct selling and as a result had been affected by everything that had happened and had no way of selling any of my products let alone put money into my account as I am stranded in another country, no response. All I have received are emails acknowledging my complaints April 21 - Query Ref ***Q, September 9th, September 9 letter of demand Ref ***9, September 16th both from Business care, September 21 from Celiwe Motseki, October 1st, October 9th - Customer resolution complaint Ref ***, Digital Banking acknowledgment of complaint Ref ***, The only call I have received in the past 6 months from Taryn Jackson who was shocked they had not tried to resolve my problem or assist me with it, but forwarded the issue to the next department who never did anything, REF Rj***, Oct 10 - acknowledgement of my complaint Ref ***, and that the last I heard from FNB till the sms from their attorneys Ref JO*** from FNB business, which I only happened to bump into when swapping my sims to keep my MTN line active as they are unwilling to contact me on the number that I have continuously supp**** them with. At this point I have no idea what to do and so upset at he fact that for a customer to get any assistance from FNB they have to take their issues and place them in public forums and social media just to get any help!
