Liquid Capital service sucks!

I have a service cover with Liquid Capital and I took my car in for service at 07:00, Honda garage where I took my car in gave me a call at 14:00 that they have been struggling to get authorisation from Liquid Capital. This means now I might not get my car today, which is an inconvenience as I did everything I was supposed to do on my side and on time. Why am I being inconvenienced as I pay my cover on time and have never missed a payment. I tried calling them and spoke to Mary-Ann who couldn't even take my number as i have been holding on for a while, she did not even have courtesy to try and assist. I am disappointed.
