Motorvaps

I have been a member of Motorvaps since 01/06/2022 paying R 861.25 for a service plan, my car had 140 000km on, the gave me a service plan to service every 10000/ 2 a year. I asked them to change it to manufacturers service which is every 20 000km/1 a year. now they stating the first service sbe at 180 000 and the payment remains R 861 p.m. How can it be the same as servicing twice a year and why must i now have to pay two years at R 861 for one service, they are ****mers i want my money back and this **** plan cancelled. Service at volvo for major is between 3500 to R 4000 i have to pay R 20 664 to motorvaps for one service absolute robery
