Failed to pay for the service.

I am so disappointed by Liquid Capital. I have a service plan with them. Last week Friday I took my car to Renault Newcastle for a service. They called me and told me that liquid Capital declined the authorisation because my kilometers were over 60000, they said I'm late for the service. I logged a complain but no feedback no one has contacted me. I called them again this morning to request a document that explains what are the exclusions on this plan, the lady Nthabiseng just dropped the call on me. I have been paying so my money went down the drain. In this difficult times financially where am I going to get money to take my car for a service.
