why are you blocking my account again.This bank is so disorgarnised

I ordered a credit card and it was delivered to Vincent branch.When i was collecting the card the lady who was helping me could not find the papers for me to sign that i have collected the card and said it did not matter.I transferred all my whole salary to my credit card so i can book a flight to go for an important interview on Monday but when i am trying to do transactions it tells me its not secure.I could not transfere the money back to my smart account.I called the call centre and the guy told me my credit card was destroyed because it was not collected and yet i had the card with me.Now i missed on an important interview, i cant pay rent or buy grocerties for my kids because FNB just blocks accounts when it feels like.Why was i not informed that they are going to block my account.The last time it was blocked because of FICA requirements yet i had gone to the bank to submit the document and i was not informed again.Its so frustrating.
