BAD SERVICE/NO RESPOND

I Have been paying for the policy since march , my policy is active , i have phoned to confirm if i can take my car for service , & i have send them all relevant documents they asked from me on the 20/08/2021 until now no respond which is a month later, i took my car for yearly service , Nissan contacted Liquidcapital their answer was policy not active yet , when i phone them my policy is active problem is i have been under quoted according to them i am paying for 95000km , when i ask a way forward all they say they have escalated the call to another department ,they dont know when they will respond , when i joined the policy for service my car was less than 60 000km which went for 4yearly service already at less than 60 000 how do they quote me wrong & deduct for 95 000km which would take me more than 3 years before i get to 95 000km , service book is yearly or every 15 000 , i wouldnt recommend any one to join them
