Help Was For Inspection

Hello people am new here and need help or advice! So, first of all to my TT. Bj 1999 ran 73,000. I brought the day before yesterday for inspection! Should be done: annual service,brems fluid service, timing belts and I thought the water pump is doing right away, the tension rollers etc. anyway. The workshop was recommended to me by acquaintances,the master has made a good impression that the timing belt must be made at 180.000km or 5 years old car what 2 a I didn’t know VW Audi workshop, I had to invest with shock!!!!!!!! Yesterday the master called me to pick up the car! The shock was big bill over 775,- Euro!!! Is that normal??? Well I thought then let you explain the bill from the master,Kamm just the usual,bla,bla,bla!!! After my question if he could show me the exchanged parts he came to stutter easily, though” said yes “but besides the timing belt and V-belt he could not present me at once anything the other parts he told me were already driven to the scrap dealer. I remained Stur he noticed that he could not get away with it and so I and apprentice to the scrap yard where we found nothing neither water pump and the tensioning rollers. Once again I threatened the master that I would put it to test if the parts were changed. He was afraid so made an appointment for next week where he would drive the car on the stage and want to prove that there was a new After the history I called a well-known master and want to visit with him before the workshop to check whether really new parts have been installed. If not I have made an announcement to reimburse against the workshop!!! EURE MEANING TO???? BETWEEN THIS HISTORY! WHEN I SHOULD BELIEVE BON SOVIEL DON’T BE ANYTHING FOR THE PARTS THAT ARE REPLACED AND NOT FOR THE AGE THAT ARE BLIED IN THE CAR!!!!!!!!! HEARING INSTRUMENTS AND THE EXPERIENCES THEY HAVE BEEN HAD!!!!!!!!!! THANKS
