Extended Service plan

I took my Nissan x trail on 11th of January 2022 for 90000 km service at Morgan Nissan Kimberley, with the understanding that it was still under the extended warrenty. When I retured at 16: 15 after no corespondence from them, apparintley they tried to contact me, the service was not done. According to then LiquidCapital said the last service was for 75000km. On 12 January 2022 I spoke to Brenda at liquidCapital. She said we signed at Honda Honda Boksburg where I bought the vehicle and there is nothing she can do about it, for the extended service 60000 an 75000 services. Nissan still paid for the 60000 km as it was part of Nissan service plan. But surely when they receive the application they should have known 60000 is still under the Nissan servise plan. At least they could have inform Honda or myself regardibg the mistake. I tried to contact Honda without sucsess. LiquidCapital only paid for one service. The 75000. I hope you will be able to help me . Kind regards Herman
