Sold a lie

I got a sales call somewhere in may and the lady was selling service plan and we had just bought a vehicle in Nove a 2018 step way Sandero I was quoted a monthly fee of R390 or R391 somewhere there ,I accepted the product as the lady even explained to us that our next service will be a major one as it will be service no 6 just after I had provided the year model and mileage ,she even added that we are under driving the car as it should have been on90k I think a month back she added,I did tell her that the car was under my wife name and I asked if that would be an issue she confirmed it’s not an issue ,I have paid my policy with no delay and now when the car needs to go for service I’m told I would need to wait until next year jan 2024 as the car would be on 90km,and when I took this policy it was advised that any time after the 4month the car would go to service as per normal when it needs to and as per the service book last service was 04/05/2022 and next service was/is @ 62000km or 12 month and. I took this policy in may and now the car is at 81330km instead of being advised when my car can go in the other one says the vin is not the same as what they have the other one says the car is not in my name ,the other one says car needs to go in next year 2024 when the car @90km spoke to Karabo ,Thato and Lesego all in client service all of whom seem to fin this matter as a joke none of them have been able to assist to resolve we have been basically sold a lie ,this is a big ****s please be aware
