While working for an HVAC company, I told my boss that I was looking for another job. He told me I didn’t need to come back, and stiffed me on some money owed.
So, knowing how the business worked, I called using apps so it was a different number each time, and made appointments for various reasons, giving fake names and addresses. Some close, some far. When they would arrive at the home, obviously the homeowner had no idea what they were talking about, they’d call the number I gave when making the appointment, I’d answer, tell the technician that his boss owes people money, he wastes peoples time and this is going to continue to happen. I especially did this on weekends as it was considered emergency services, after hours when technicians were expected to leave home and go, unpaid unless they sold a service and they’d get a commission. Each time I’d tell the tech that his time was wasted bc his boss owes people money and suggested he collect something from him for his time.
This obviously pissed off the techs who eventually would not accept a weekend “on call” job, a couple looked for other companies to work for. I know the the GM was the one who eventually would take the emergency calls so his time off was ruined as no other tech would volunteer to go, guys left but is hard to know why as they would always come and go.
There was an initial charge just for every service call, I did this until the money that was owed to me was repaid by what they would have collected on the service calls.
