Poor customer service by Suzuki

We bought two Suzuki's in the last year, the first of which went in for a service at Suzuki helderberg, whom after they serviced the vehicle informed us we went above the allowed mileage and if we wanted to keep the warranty in tact we had to pay for the service. We even handed the car in early. Long story short, it was found that they entered the next service figures incorrectly on the log book and was told to pay is back. After 7 weeks of nagging and constant excuses we finally got our money back. Not only that but our Facebook posts were deleted by them. I seriously regret buying Suzuki's and won't make that mistake again. Not a single apology from them or any indication of regret. Seems this is normal service levels
