"Too late! I messaged you on here and also by text 10 days ago. I also suggested leaving the remaining plants as I hadn't heard back, we went to a garden centre and got what we needed. We are happy with the work you did, but you just never kept in touch and never replied to messaged. We consider the balance paid to you already full and final settlement"
Had a gardener in to replant some beds. He had previously not kept in touch prior to the work he did, but he needed to come back as he hadn't got some mature rosemary, mint and other bits he'd quoted for. And he didn't reply to this either!
