Shocking bad Service

Do NOT go to Hyundai Boksburg Corner Rietfontein and Bass Street ! Bad service and bad experience! Every year we have taken BOTH of our Hyundai cars for their yearly service to Hyundai Boksburg . Every year we have experienced unfriendliness and unprofessionalism from the admin lady that prepares the invoice for us , but it was convenient for us as we are very close to this Hyundai, so we put up with it - until now. Well needless to say - never again! On the 28th Feb our Hyundai went in for the yearly service. Ours was the first in - but last out. We collected the Car just to find out a few months later the service record book was not stamped. On top of this the invoice we received was our registration but someone else's name and address. We went back to see them and managed to get the book stamped but now they cannot correct the invoice as it is older that 3 months. We usually check this but because we were in the process of moving we neglected to do so - trusting that Hyundai works with integrity and honesty. When we ask the admin lady to fix the invoice - she said it has to go to IT as they cannot fix it themselves. She was supposed to have given us feedback and we are still waiting. Not customer friendly at all . So who knows when or if the invoice will be fixed?Needless to say we will be taking our cars somewhere else in the future.
