Non delivery and refusal to refund

I purchased couches from Atozfurn, I explained to them that I cannot take time off of work during the week for the couches as I work and have nobody to open my flat for me and they agreed that they would arrange for delivery on a Saturday as soon as the couches were made and ready. I was informed the couches were ready and they advised they would deliver 23/03. I was away but arranged for a friend to wait for them and supp**** their driver with her number. No show and no phone call to advise why there was a no show. I then called the driver who advised they had collected the wrong colour couches and would deliver on Monday, I explained I couldn’t as I work but the coming Saturday would be fine. I emailed them during the week to find out when their driver would be there, no reply. I then phoned their driver that Friday and he said he would be there at 9 and again, no show so I decided after 2 weeks with no couches I would buy from a reputable retailer, therefore I have no need for the couches form Atoz. Please also note I paid for delivery upfront!!! I then emailed them asking for a refund and they are refusing to refund me as they say “Not being available for deliveries during reasonable hours and days does not automatically entitle one to a refund on custom made items.” According to the CPA suppliers are required to honour the supply of goods or services on specified dates, times and other participants, if committing to such arrangements in reservations or bookings and as a consumer I am entitled to a full refund, over a month later and I'm still waiting to get my money back. Their excuse? Couches were made specifically for me, but these are standard size couches, I didn't ask for any different specs and they could easily resell these couches to someone else. Do not buy from these people!!
