Theft after paid up account

On the 16th of April 2024 I got an email that they want to finalise my account to ownership. I explained my boss didn’t pay me yet and would sort it out I did a bit later then I promised. Round mid may I sorted it out. This morning I get another rental invoice. The 6 June I received correspondence that I must pay. I sent an email the account is paid up. What the hell is going on it’s paid up. Are you people ***********. For 33 months without getting paid I have made a plan to pay my account what more do you want from me. It’s paid in full leave me alone now.
