Terrible Service

My vehicle went in for a service on the 13th January 2025. I clearly asked the service advisor if my service book was stamped when I went in to collect my vehicle, he said he was getting it done. I get home and find the book not stamped. A week later I get a call to find out how was my service experience, I explained to the lady about my book not being stamped and she advised they will arrange for the driver to collect my service book get it stamped and drop it off again. We are now almost at the end of March and I have not heard back from them or had any assistance regarding this matter. The service levels have dropped drastically at Hyundai Pinetown, I have been dealing with them since 2013 and its shocking how terrible the service has become.
