Worst service & Incorrect item delivered

I purchased furniture on the 12-09-20 from the store which was paid for in cash, I was advised that the headboard was in stock and the other items (pedestals and the Cali double bed) were not in stock but I should receive everything within 10 working days. We didn't receive any calls or update and on the 21st September my husband called the store and was advised that they had received everything excluding the headboard (which was apparently in stock when I made the purchase) and they could not confirm when they would receive stock. My husband then requested that they deliver everything else and then they would deliver the outstanding headboard when stock arrived and they advised that we would be charged for delivery for the headboard even though I have already made payments for delivery for everything when I made the purchase. The items were delivered on the same day of the call (21-09-20), one of the delivery guys was rude and told me to sign as they did not have time to waste even though I wanted to check if their papers did not include the outstanding headboard. I had to then drive back to nothriding the following day to get my refund after the rudeness of their delivery people. On Saturday 26th September when we decided to assemble the items it turned out the Gamma 3 drawer pedestals delivered do not even match (one is Walnut and the other is Wenge) even though on paper it says 2x Gamma 3 drawer pedestal- Walnut. The store is beyond *********** and I am beyond disgusted with the service I received and feel like I wasted my hard earned money. I am to a point where I am tired and know that I would now yet again have to drive back to the store with my petrol to go demand for them to change this even though it is their mistake. I paid for delivery for my own convenience but that place doesn't even seem to care.
