lack of service rather than service

Hi I booked my car into a service at barrons bellville on making the booking I asked the lady I need a book for my car as my book is full and I cant use it anymore The lady said I must hold for the parts department spoke to a guy that said they dont have the book but they have for the POLO and that is the same as my Jetta so no problems there Im happy please order for me Here is where my problems start the service was done on the 9 may 2018 They serviced my car telling me that a fuel filter is not part of the service ,I have had many vw services with different models and accourding to my book all other service had fuel filter replaced The Invoice since they did not order the book that I asked for was wrong they invoiced me 15000km wrong did not even bother to look at the Km on the car so no book no invoice to show the car was serviced so no record that is correct even the paperwork is wrong and I am now stuck with wrong data so today on the 10th may my car oil light comes om I had to put in 2 punts of Oil they did not add the right amount of oil So R6000 to have a service done that no extra work was done dont even change my fuel filter and did not put oil in my kar I could have damaged my car permanently and they dont care at all THIS WILL BE MY LAST VW SERVICE I WAS IN THE CAR FOR A NEW MODEL I WILL THINK LONG AND HARD BEFORE I EVER GET A VW AGAIN
