Debited for service plan they claim it has expired

This is the worst company I've ever had to deal with, i took out a service plan with the company and was told i could take my car to service after I've completed my 20 000km from my last service. This was going to be at 110 000km. When i reached these kilos, innovation group told ford that my service plan has expired. This was before any service under the plan. Then i called, they said they are amending the policy. Then i serviced my car. When i fetched the car. The dealer said, innovation group informed them its my last service. Then i called the company after seeing that they continued deducting money and the agreed kilos had not been reached. The agent said i could take my car at 30 000km and that he was send my documents for amendments. I never got communication from last year September 2022 and they still continued deducting. Today i call and im being told the amendment didn't go through. Whatever you do, don't take out a service plan with this company.
