bad communication, poor services and rude consultants

i took my car for a 90k service last year, i took it again this year for a 105k service.the dealership called me notifying me that that the accessory belt is worn and was supposed to be replaced on the 90k service that was done last year but was never done merely because LIQUIDCAPITAL didn't authoirzse .Renault wanted to replace it on the 105k service but still LIQUIDCAPITAL didn't authorize .i called them numerous time to find out the reason of not authorizing and i was told to provide my Natis document of which i did.when making follow ups, i was told that the information i gave them when taking out the policy was not the same as the one in the Natis document and as a result it was wrongly captured in their system which is pure lies.i was under the impression that after proving them with the Natis Document the matter will be resolved. when i checked on the policy documents that they (Liquidcapital) have sent me the information is correct,even when i logged in the website the information is correct and i feel like they are just looking for a loop hole not to pay for the belt. i called them on Tuesday just to follow up with the case and i was told that they are waiting for a call recording between me and them to verify if I said the car model is 2019 or 2017 .None of my Email has ever been responded neither did i received a call from them. I've spent a lot of airtim following with this . According to renault Specs, the belt should be replaced in 90k or in four years, whichever comes first and in my case the 90 k came first. Liquidcapital is out to rob people.right now my car is packed at the garage with me fearing the worst case scenario that could happen to it should i drive it.i have proof of numerous calls that i made to them as well as a bunch of emails not responded to.
