A company contacted me about their custom ticket system not working

Then after asking them couple things they just wanted me to look at emails they found stacked and lost in the ticket system archive:

One clients ticket somehow got caught in between updates and hes been answering the auto close notification (each ~3 days because it never got closed) of the system, with ranging from "yes, thank you, I have solved the issue" escalating to "why dont you leave me alone, I have told you, I have fixed it, please stop", poor guy 🤣
