So disappointed

I'm so disappointed with this honestly. I was selling an item with an idea of upgrading the next day. The buyer was using a standard bank account just like myself. What a relief 😌. He transferred the money into my account immediately and we were all happy. The money shows under my transaction list as well as the overall balance but not as an available balance. I can't use the money and I'm loosing the second deal. I've used other banks in the past but transfers between similar banks were instant. I mean instant not even 5 minutes apart. I'm starting to hate standard bank honestly.
