Stop ****ming people!

Regarding the botched repair on my oven four months ago: the door remains off its hinges due to your technician's negligence. I have attempted to resolve this amicably, but you have stopped responding to my messages. This is my final notice: if this is not repaired within 7 days, I will be forced to take this matter to the relevant consumer protection authorities. Stop ignoring your customers and fix your mistakes.
