Hastings YouDrive Cancelled

Hastings YouDrive policy was cancelled earlier today due to the fact I asked a question

I asked the customer support whether i was allowed to do a dominoes delivery driver job in the car and they said no. I asked to speak to a manager higher up and the woman on the phone said the manager would call me in a couple of of minutes and hung up, the manager never called so i rung back and asked another agent the same question, after these calls i got an email that Hastings has decided to no longer insure me.

I rung Hastings back and they said they will look into it, after finally getting through to a manager the manager said she had listened to the call and told me I said it in a way of that I already was doing deliveries and already was insured by dominoes which was against their terms and conditions, i explained it may have sounded like that but I asked to explain further to a manager at the end of the first call but didn't ever get a call back before my policy was cancelled. Is there anything I can do about this?
