RL was subcontractor on a kitchen remodel. Three years later, out of the blue, they served with certified letter announcing their intent to sue us because our contractor allegedly hadn't paid them for part of the job. We never hired RL, we never had any direct relationship with them, we never got a bill from them. They are cozy with our contractor (with whom, BTW, we had to terminate after a 30+ year relationship). Apparently, our contractor had been in RL's office the day before, claimed we hadn't paid HIM for the job, and on his verbal say so, RL demanded proof of our payment to the contractor, or, as they said threateningly, "We'll see you in court." This was extremely unnerving to people like us, who pay every single bill as soon as we get it. When we did finally get a copy of the invoice, it was made out to the contractor, not to us, and didn't even have our correct names in the space for customer name.
