FNB not putting customers first

Sars did a verification of banking with FNB for my refund to be paid into. FNB verified the account. yet when sars deposited the Money FnB Put a hard hold on my account. The shocker was when i spoke to FNB on the secure chat i was told to contact SARS because SARS had put a hard hold on my account which doesn’t even make sense. I have been on the phone between SARS and FNB for more than 6hours since yesterday. I Spoke to someone at SARs today who said that FNB must sort the issue out. I then Called FNB and they said there’s nothing that they can do. It takes 7-14 days to bounce back to SARS then i must now still wait 21 working days for SARS to verify another bank account for me. I requested that FNB upgrade my current account and keep the bank account number and the lady said it’s not possible. What pathetic service from FNB. and then still blaming SARS for blocking my account. Why verify banking details with SARS if my FnB banking account isn’t allowed to receive SARS Payments and why not tell customers this
