Bad service

I took my vehicle for service at BMW Centurion Lynchen on Thursday the 21 Jan 2021 as booked, i told them my motorplan has lapsed but i hv a service plan with MotorHappy Liquid Capital and they must liaese with them, i gave them my plan number and their contacts and left , later in the day im called by Shannin at BMW and told that they will not release my car until the payment for the brake pads is released as only the service payment was released, so the car will stay overnight. Ok. Friday i call the dealership and ask what is going on , im told that Liquid Capital did not approve my claim so i have to pay the R3K or else i wont get my car, I paid the money and called LiquidCapital to find out what the hell is going on, my plan is up to date, why then is this not paid, and how am i going to be reimbursed. They tell me that the dealership was supposed to send them pictures of the brake pads before they approve the claim, only 1 pic of the brake pads was sent and they need 4 pictures, they cant process the claim until they receive the 4 pics. Tueday 26 Jan BMW finally sents the pictures to them and and the matter is sent to Technical for approval that i should wait. I get a call from Nthabiseng and I'm told that Hendrik did not approve the claim and that im *****ed because he doesnt have proof that the pictures send by BMW are brake pads of my car. How is it my fault that BMW and LiquidCapital and Hendrik have qualms and I have to pay for it when i pay my debit orders monthly? If Hendrik wants proof that the brake pads are mine why must it be my problem and not BMW? Is Hendrik approving claims because he believes and has proof that the pads are mine or because the car was serviced and pads were changed?
