Terrible communication and a 5-10 day wait for their mistake

I generally think The Courier Guy is a good service, but my recent experience has been incredibly frustrating. After double-checking with both a branch and an agent via WhatsApp that they could ship furniture, I paid upfront. On collection day, the driver arrived and refused the load, stating they don't do furniture.

While they were quick to take 100% of my money upfront, I am now told I have to wait 5 to 10 days for a refund. I understand financial protocols, but considering the error was entirely on their side due to conflicting internal communication, making the customer wait this long while jumping through administrative hoops is unacceptable. Great at taking payment, poor at resolving their own mistakes.
