Dial-and wait-a bed

Bought a bed on Friday 14/06/2024 - admittedly the initial service in the shop was good, the salesman was knowledgeable and affable. Delivery was arranged for Monday and I was advised that an invoice would be emailed to me later as their system was down at the time of purchase. I didnt receive the said invoice over the course of the weekend and then also realized that Monday was actually a public holiday. Anyways, I called the shop on Monday and the salesman said he had also completely forgotten that Monday was a holiday and that I would be contacted by the warehouse, once work resumed on Tuesday, to arrange delivery. I also asked for the invoice to be sent, advising that I had not yet received it. Here starts my problems. I was advised that as an incentive for my sale "free" delivery would be thrown in - upon receiving the invoice I noted that delivery was charged for (albeit worked into the total price). I understand sales pitches and I understand that costs need to be covered but this just didn't sit well with me. Rather just say that here is no free delivery - that is completely understandable. Don't say sonething is free and then show the charge on the invoice. Just be transparent. I wonder what would have happened if I had not been told of the "free delivery" - would there have been an additional amount charged which would would equate to having to pay for delivery twice? The first one, which had been worked inro the price and second, a visible rate. Most annoyingly though is, I never received a call yesterday from their warehouse and was going to call this morning to find out if my bed is being delivered today (Wednesday) but then got a call from said warehouse only ro tell me that it will only be delivered tomorrow (Thursday 20/06/2024). So after initially arranging for Monday (fully understand it being a public holiday so logically speaking it should be moved out by a day to Tuesday) I now am only to receive my purchase on Thursday afternoon. Almost a full week later. My "free"delivery is costing me in more ways than one.
