Standard Bank business account money HANGING

I have a business account with Standard Bank.On 9/4/2024 I transferred R2600 immediate payment from FNB to pay rent to City Property. A few minutes later I see the money reflecting on Standard bank under available balance. I tried to swip R2500 it said "insufficient funds" I transferred R150 and tried to swip again it said "Insufficient funds" again. However the amount shows on the statement that it actually went in but never went out because it shows OUTSTANDING CARD AUTHORISATION on the statementnot NOT insufficient fund. I went to the bank today ( Pretoria CBD), the person assisting me asked if my banker tried to help regarding the matter I said NO because I've never spoken to 1. Then l her team leader said the money is "HANGING SOMEWHERE" since I did an immediate payment and tried to swip minutes later(I don't know how many minutes I should have waited before using the card). They stated a few departments of theirs but still said they won't help me because the money is "HANGING" They said they will ask the Card division but they don't see anything happening because the money is "HANGING SOMEWHERE". Kindly assist
