Very Dissapointed - MFC INNOVATION GROUP

I would like to express my regret for choosing innovation service plan , it is my second time taking this plan against my MFC vehicle finance... and it is the second time that i was messed around by the sales consultant at Innovation

I took a second time service plan on my vw polo gti and i asked the lady before taking the plan if the coil packs will be covered and she said yes ... My car went for 206km service and the spark plugs were not covered ... only oil change ... which i was not aware of ... My car recently went for 210km service and again only oil and filter change ..why was i charged so much on a service plan if the main part of service is the spark plugs .. my car has been for a service and now my spark plugs are worn out as i was told it would be changed but it was not .. I am very disappointed and feel that i spend a lot of money on this plan and i could have paid for my service privately .. because i have to spend more of my own money on a proper service ... both services cost less than 2k but i am sure i spent more than this with the service plan i procured .. i am highly disappointed that the innovation team does not know what the plan covers and now i have to take on added cost due to their inability to understand what is a coil pack and spark plug
