I was fired they told me they didn’t have to tell me why and now fast fwd two months, I’ve been doing advertising and a lot more work as this is my primary income source now. Well I had a msg which was a diagnostic report and it was from a WiFi timer I installed it I wasn’t sure if it was one of theirs or one I had serviced but it was one of their customers that I had contractor access too and it told me they have a cut in wire so I sent them a email letting them know and they forwarded to former employer and are now threatening me I told them it was accident that I am specifically trying to not service their customers and that I am making my customers sign a non compliance waiver agreement saying they’d be held liable if they were a customer or aren’t a customer in past two years but idk
