Go down to your local court and ask the receptionist or clerk of the court, he/she will give you the correct form, and any advise you need, there is a small charge for this but it could be worth it to get your money or satisfaction, don't forget to fill in all the details, take all the paperwork with you to prove you paid for more than you got etc, plus her insulting letter, and whatever you do do not forget to take the information to show the Judge on the day of the hearing.
