You are on a losing wicket - as it is the sender not the recipient that must make the claim. Under the Distance Selling Regulations it is up to the sender to ensure an item gets to you and if it does not for them to refund you. So any action is up to the sender not you. Unless you can actually prove a postman has stolen your items you are leaving yourself open to action particularly when you make these accusations on an open forum. You being convinced your items have been stolen is not proof and this will not be seen as proof either as what you state is simply deemed as hearsay. You will get nowhere with this in any legal action contemplated either unless you have actual evidence to show the item has been stolen and by whom.

Obviously they new about the air con problem but you didn't play along and just accept, so off you your money back so they can sell it to someone else who may not make a complaint but just go and get it done themselves. This does sound like more than a regas, I can't see them giving in so easily of something so simple. The contract included your old car so they must return that as well as a full refund. Do the refund and get your money back and then you can tackle them about consequentials. If they refuse to help cover what you have lost, make a complaint about their breach of contract and the damages you want.

If the clowns keep knocking after you have told them to 'go away', then I would be ringing the police and stating that there is someone on your property who will not leave when told to do so, and is causing a breach of the peace, guaranteed to scarper when they hear the nee nar coming round the corner! Personally, I'd go into the kitchen, fill up a bucket of water, then open the door and throw it over them, they'll get the message then. ruddy parasites.
