Held "hostage" while awaiting an immediate payment to reflect in third party account

Bought some furniture from a private seller. Arrived with moving truck to collect furniture. Did an "immediate" transfer to the seller's bank account. Nothing arrived. Movers making noises about charging extra for waiting. Husband left with furniture in the truck leaving me as surety in a house with an man not known to us, where I called the bank- waited 24 minutes for call to be answered and was transferred from one person to another. Upshot, 40 minutes later, is that I was infirmed that "immediate" takes two hours if I am transferring to a new beneficiary. I had to wait the full two very uncomfortable and awkward hours before the "immediate" payment arrived and the man let me leave. Standard Bank - please refund the "immediate" payment fee and compensate me for the extended phone call costs. Thanks to Busisiwe from General banking, who although she could not help, promised to call me back and see that I was okay, which she did. Standard bank needs to put a note on the banking app explaining that "immediate" payment may not mean what it says.
