Innovation group dishonesty

I was called by the consultant and I did purchase an external warranty for my car on the pretence that everything will be covered and I'll have no issues. I was told that I need to have 3 premiums paid so that it can be active. I agreed. I have covered my 3 months payment. My car went in for a service and they discovered that a few other items need attention. I supp**** my warranty details. The dealership called innovation group and they state that the policy is not active. I called in and they stated they will escalate it as they can see the 3 premiums. We waited couple hours and called again. And the same issue. They waiting for it to be active. I then called back and the one agent helped me to say that it was sorted and the dealer can call in. When the dealer calls to submit the claim, they notify him that I don't have cover for some parts and that I only have cover for 10500 and I'll need to pay in the balance. I was distraught. I am a very hard working individual and gave innovation group the benefit of the doubt when taking this warranty out as the consultant stated I will have no problem when claiming as all issues are covered. Now just for a few smaller parts the agent stated that I'm not covered. It does not make sense. I am asking innovation group to sort this out immediately and cover my Total costs and not hide behind their wrong doing.
