It was new and from a dealer.

Hi We bought a campervan in Scotland earlier this year. It is a three berth campervan, designed to take two adults (parents) and our daughter. The van was in stock. We specified a third bed kit when ordering the van. The salesman looked in the manufacturer's brochure to find the price, £295, and added that to the overall cost. When we collected the van we commented that the third bed kit wasn't to the same standard as the rest of the van. The salesman said that he hadn't seen a third bed kit and that this was what came from the manufacturer. The first time we tried the third bed it collapsed when my daughter sat on it, leaving a piece of wood with 4 long screws sticking out lying on the floor next to her. When we told the salesman he first claimed that this was that was sent from their UK supplier, but eventually admitted that they had the faulty third bed kit made as it would have cost them ~£860 to buy the correct third bed kit from the manufacturers. Eventually, they agreed to replace the bed kit with the correct one. Their initial timescale was 2 weeks, increasing to 3-4 weeks. However, it has take over 10 weeks to get to this point and it is still not complete. The bed was delivered in sections, with the first delivery missing a number of vital items that the supplier had not noticed were missing until I informed them. It took them several deliveries to fix this. There is still one small, but important, piece missing. The firm has emailed to say that they will no longer accept emails from me and that I have to send anything else by recorded delivery. This is since I put a post on the manufacturer's FaceBook page asking for help. I have had to chase the retailer for any information, and have written at least 27 emails. We have not been able to sleep properly in the van for this 10 weeks as my daughter has not got a proper bed. As the main reason for buying a campervan is to sleep in it, and that the reason we cannot sleep in it is due to their failure to provide the bed kit that I thought that I had ordered from the manufacturer, and that the supplied kit failed, is it reasonable for me to be able to claim compensation for: a: the cost of my time in sending emails and chasing them up, and b: a sum for loss of use/enjoyment of the vehicle during the time I had to wait for the replacement? This is particularly relevant as we have just had half term and have not been able to use the van during this period. Any assistance would be gratefully received. Thanks
