False Information and no accountability

I visited Opel service department to confirm the status of my vehicle's service plan, as I was unsure when it was due to expire. I spoke to a lady at the service desk who then checked with one of her colleagues. After confirming, they assured me that my vehicle was still covered for one final service, and I was advised to bring the vehicle in on Wednesday, which I did. Today I was contacted around 1:00 PM and informed that I had been given incorrect information — that the service plan had in fact expired and I would now have to pay for the service myself. This is unacceptable. I planned my schedule around your team's assurance. Not only was I misled by your staff, but I was also left without my vehicle the entire day, relying on Uber at my own cost, all based on your team's error. I am now expected to pay for a service that your team had confirmed would be covered, which I find extremely unfair and unprofessional. This situation shows a serious lack of communication, internal accountability, and customer care. Your staff provided false information, and now your company refuses to take responsibility for it. This experience has left me feeling disrespected and disappointed in the Opel brand and William Hunt Fourways in particular. Even after I spoke to the service manager, he did not do anything about it.
