How to be ripped off in Larnaca, Cyprus

We hired a family sized car for our holiday in Cyprus this year, made sure it was big enough for 5 as our children are as tall as us! Never had a problem in all the years we have been travelling to Larnaca. Upon going to the Europcar desk we were informed that the largest car is a Nissan Note not a Ford Focus! slight difference in boot size etc..... thank goodness we only had hand luggage we would never have fitted a suitcase in the boot. We had purchased full insurance as well when booking and the paperwork specifically mentioned that we did not need to purchase anything else to cover us, but no we had to pay yet more money as we were specifically told that if we had an accident or any damage or even any problems at all they would not come out to us or cover us for anything unless we purchased their insurance. So all in all do not book you rental car through easycar.com or Europcar, it is a ripoff. Have emailed and complained and have received a small refund, doesn't cover what it cost us and have received no explanation either. We were not the only ones with this issue out there, general feeling was someone was on commission!
