Poor service at Liquid capital

I took my car for 75000km service at Midrand last month of January.2023.My claim was rejected and told to wait for the 4th debit ,which was the 25th of this month .Still today I took my car for Service at Mitsubishi Midrand this morning.They called after twelve to let me know since the e mail was send to liquid capital this morning for approval,and they rejected my claim again. I'm so frustrated,I called their customer service and told the km had exceeded the required service.Then I refreshed their mind that,it is because of them rejecting my claim.Im so worried because according to the looks it shows that the plan will lapse without any service rendered to me. Then will have paid for nothing.Since I called to they promised to call me back,I'm still awaiting their call.
