Poor service

I bought my pre owned vehicle in June 2020 and it was at 53000km,thats when I took up the liquid Capital service plan, the agent advised me that I need to take the car for service when it reaches 65000km, now when I contact Hyundai I am told that liquid capital won't do the payout as the car was supposed to be bought in at 60000km,when I call the call center I spoke to Susan, who was very rude as she told me that I have to wait 2 weeks to get feedback of the recording, I told her I don't have 2 weeks on my time but she was very rude, sent an email and till today no response.
