Beware! Cartrack Money Hungry

I've put in a cancellation request as the vehicle no longer belongs to me. Bare in mind I've already paid a premium for the month of April. Now they're saying they're going to debit me again at the beginning of May, for a vehicle I no longer have and won't be getting an benefit from! Such a ridiculous approach. And here i was going to have my new vehicle with them, but rather not. I'll be taking my business somewhere else!
