Yes, he is not accepting responsibility.

Would I not be suing the right entity I put the name and address of the business on the claim?

Can't I just put the name of his shop and its address on the claim?

Hello everyone, I'm having a problem with my local phone repair person, I gave him my phone to change the screen and paid £100 for it, they have changed the screen but now the home button doesn't work and there seems to be some dead spots on the screen as I can't type some letters in. I have tried solving this problem with them but he demands another £70 for fixing these issues, my phone is only worth £200 2nd hand, so that is really unfair. It's important to note that those features were working even when the screen was cracked. My only option is to take him to small claims court, and I need some assistance with that please. I don't know the person's name but I know that he's a sole trader, do I put his business name on the claim. I also don't a have receipt, but I have a reward card with one stamp that gives me a discount on my next purchase, also my bank statement shows that I have withdrawn that amount on the day, do I have any chance of success in court? Thanks for your help
