My mother has fallen victim to a rogue builder. 2 and a half years ago he began replacing her garage roof for her. He was sketchy even then, often not turning up etc. When the work was nearly but not quite complete he said he was coming to pick up the money as he needed it for Christmas. He left a ladder and a workbench so mum (in her 70s) naively paid up in cash. Since then he has not returned. He often doesn't answer his phone. If he does he is apparently always having some drama so he can't come, or will give a date and not turn up.
This is obviously a lesson learnt for mum and we have no legal leg to stand on as there is no contract and payment was in cash.
I want to simply annoy the hell out of this man and inconvenience him as much as possible. I have his full name, address, mobile number. I'm thinking signing him up for spam mails and things like that.
He seems quite a highly strung, chauvinist type so just little inconveniences will hopefully really irritate him and give me some satisfaction.
Any ideas?
