Frozen account with FNB due to FNB private bankers being ***********

I have been a FNB Client now for more than 1 years. In August I received an email from KYC that I had to verify my account and therefore I had to provide a copy of my ID, copy of my residential address and proof of income. Which I did. On the 30th of August I emailed back my private banker Lesego Malefetse with all the required document. On the 13th of August she emailed me back and said that she has received all the required documents and that it’s all been loaded in their system. Should she need additional information she will let me know. This last monday on the 10th of September I received an email from the KYC department saying that I still had not provided the documents and that therefore legally the bank can freeze my account. On the same day I reached out to both Lesego Malefestse and Xolizwa Kadide. Lesego emailed me back saying that everything is ok and that she has loaded all the documents in the system and is waiting for update. Needless to say that none of the above was true. Yesterday I found out that my account has been frozen and the only funds I have is sitting in that account. I have 0 cash on me and it’s the weekend. So I spoke to Lesego again and she admitted that the bank has made a mistake and that my account should have not been frozen. She said that she resolved the matter with KYC. 24 hours later and I still cannot access my funds. At this point I am beyond frustrated and I demand that the bank comes with a resolution. I want to have access to my funds. They have no right to hold on to that. How can a bank as big as FNB be so ***********. Please get back to me ASAP!
