Poor Service

My service plan for my vehicle ended in March 2019, so Liquid Capital contacted me to extend it for 2 years or at 75 000 kilometers. I was told that i will be able to service my car after 3 successful premiums. This morning I took my car in for service at Hyndai Hatfield and was told that I am only covered from 75 000 kilometers, which was not the agreement. I called the customer care and I was told that they are fixing it and treating it as urgent because my care is at the dealership awaiting service. I called them back to find out how they are and the lady said my query is "locked". As I write this I am still waiting and it does not seem like my car will be serviced today. I am so disappointed.
