Theft

i sent my car to hyundai pinetown in March 2016, hyundai 2010 ix35 2L. my car had engine cover and i know for a fact that it had a cover. to my suprise after a week from service, i noticed that the cover was missing. immediately i went to hyundai to report this. i was sent from pillar to post and nobody seemed to know anything about this. eventual a white guy i forgot his name who was a manager then, told me anyway 2010 models have no cover, yet in my engine it shows that it was taken out. then again October 2nd, 2017 i sent my car again for another service this time, car mats were ******. i did not even bother to go back to them because now i can say those guys ***** customers' stuff maybe to replace others. i want my car engine and mats back. they must check on their system for all the details who was in charge then and who was handling my car. i service my car with them all the time but there is too much theft going on now they have to be exposed and dealt with. i want them to contact me and return what is due to me.
