they service is very much poor

I did have a mechanical warranty long time ago and I also make a monthly payment, there is no default to my surprise they fail to paid my service provider or mechanic when he make a claim, they tell him that my warranty is lapse in the end of June 2020 and my car was with mechanic around May 2020, but on the 15th July 2020 budget take the monthly fees where's it lapse and never pay the mechanic. I also make call to understand exactly what is happening with my warranty as my service provider waiting for the payment. when I call Budget they refer me to Innovation for warranty, but budget is the one who collecting money on behalf of Innovation but are failing to help me or to realised the money to mechanic. I also tell them to call me but both fail to do so. I did send am email to them and CC the service provider also fail to help and I don't have a number phone or email address for Innovation as I use to communicate with them via Budget. bad news I have an insurance with them for mechanical warranty and car insurance. how should I trust them when they fail to pay a little money to mechanic.
