Disgusting Service from Day one and a lot of Unprofessionalism from Renault and its Staff

In 2020 i bought a Renault Kwid and i was told it comes with a 1year free insurance. Until i got read the fine print and noticed it is just a ****, and recently i learned that there is a lot of things that where not explained to me during the collection of the car. in 2021 the car had an issue and i took it to Renault Centurion and told the Warranty will cover the cost. when i went to fetch the car i found the 15k service done on the car while it was still on 14200+- without even being told. The service manager told me they will give a discount on my next service. when my car was on 30k and was supposed to go for service i didn't take it because i was affected by covid financially like every south African out there. not knowing that even the 30k service was suppose to be covered by the service plan. i then only took my car for service after it had excided the service interval with around +_6k. Only then i was told the car still had service plan and it is not going to cover my service. I mean if i knew that the service was going to be free why wouldn't i take the car in for service when the time was right??? I ended up having to pay cash for that service which i feel was unfair. To show how unprofessional Renault people are even today my service book is not stamped for the 15k service that was done without my authority . My car now has the same value as the car that was serviced at some backyard in some township. I really regret doing business with Renault because from day one i was treated like an idiot.
