I have been sold a faulty vehicle by a second-hand car dealer. The place is in the United Kingdom. According to the Consumer Rights Act 2015 I can claim a full refund if I request it under 30 days. But then I didn't do that cause of my ignorance, I did though notify him about the issue in less than thirty days. Long story short, I am chasing him to fix the car now, but he is always difficult to catch, I have been chasing him for a couple of months now.
I once sent a letter with a deadline, then I reached to him online and he said that he did not receive it. I used the address on the gov.uk page where his business is registered. It was recorded and someone signed for him.
I have two questions.
Firstly, according to Consumer Rights 2015, is there a deadline from when the issue is raised to the trader to then taking action to fix it, or is it based on what deadline I set on my letter?
Secondly, if I do send a letter, for instance, notifies him for court, to which address should I send it to? His official one in gov.uk, where he claims he didn't notice or his yard? What is the legal sound thing to do, for then the judge to tell me that he wasn't notified (Is that a thing)?
