PROBLEM WITH MY SERVICE PLAN

Im very disappointed and frustrated with my policy. I boight a Toyota Quantum from McCarty Toyota and yool out an extended service plan till 140000km which i paid for when i putchased the van. I took it for a 120000km service and was informed by Mccarthy Toyota that my service plan has expired on the 27th May 2019. This is so funny because i did a 110000km service at Mccarthy Toyota in July 2019 which you paid for. Apparently someone captured the wrong date and i spoke to Shadrack at customer care. He informed me about this and told me he logged a complaint and is awaiting feedback. I am still awaiting feedback and Mccarthy Toyota is refusing to release my vehicle because they expect me to pay for the service. This had happened before and the previous service e advisor told me i don't have to worry and that everything is sorted out. So now i sit without a vehicle for the weekend which was bought for my son who had cerebral palsy and i need it to transport him. I am so frustrated and disappointed. I don't care who's fault iy is i just want it sorted out asap. I refuse to pay R3800 for a service whuch i paid for in advance. My registration is LOGANDP WP, i need feedback asap Francois Du Plessis. ***
