Poor Customer Service

I signed up for their service & a year later I was in an unfortunate situation whereby my vehicle was a total loss which now we had to terminate the contract, the contract was verbal. They are now charging me an enormous amount claiming i agree'd to it. I have asked for recording & they've not been able to provide it to me.

If there are charges, the charges must make sense what i am paying for, I cannot be paying for the remainder of the contract for a service i am not using.
