I was selling a phone and informed the buyer that the left speaker was broken. To the best of my knowledge, that was the only issue that I remembered the phone having, other than that the phone had served me fine. Agreed on a price point and met up with the buyer. Allowed the buyer to check the phone, which he did - he checked whether it could connect to the wifi, whether it could read his sim etc. etc. So i sat there for close to 20 minutes waiting for the guy to give his stamp of approval on the phone. He told me he was happy with the phone and offered me the money. Took it and we parted ways. Next day woke up to notifications with him spamming my phone with messages about how much of a scammer I was and how he was going to report me to the police because he discovered that my phone's microphone was spoilt and so he could not make calls. He demanded a refund which i politely said no to because I had allowed him to check the phone, and it wasn't my fault that he did not check it thoroughly. Now I'm just wondering if he's right and I've broken the law? He won't stop blasting my phone with messages about police and all this **** about consumer rights and the lemon law and yada yada yada.
