***** WITH VIN NUMBER

I bought my car brand new from KIA.My car is due for a 30K service.I took it to Midrand Kia for them to tell me that they cannot service my car as my car already had a 30K service. They said that someone in Menlyn booked their car in USING MY VIN NUMBER!!!! NOW NOBODY WANTS TO RESOLVEDY ISSUE!! THIS WAS IN FEB!!!! NOBODY CALLED OR GAVE ME FEEDBACK I CALLED BAC A MONTH LATER AND CHERINE GAVE ME A NR TO FOLLOW UP WITH LIQUID CAPITAL.They advised me that it had happened to other ppl as well but got resolved within 2 days!!! It is now MAY!!! I LOGGED MY COMPLAINT ON FACEBOOK. FACEBOOK SAID ISSUE RESOLVED BUT WHEN I BOOKED MY CAR FOR A SERVICE AGAIN, THEY SAID THEY CANNOT SERVICE MY VEHICLE AND ISSUE NOT RESOLVED. IF MY CAR HAS ISSUES and gets damaged then KIA will have to pay as they as DENYING MY SERVICE AND I AM GOING TO SUE FOR *****!!!! THIS IS *****!!! WHICH CAR USED MY VIN NR FOR THEIR SERVICE ????? WHAT WAS THE NUMBER PLATE??Was there an investigation done? If this happend more than once, IS THIS NOT *****? I WANT MY SERVICE KIA!!! I AM DUE FOR MY SERVICE AND I AM GETTING MESSED AROUND.PATHETIC! ! DISGUSTING CUSTOMER SERVICE
