Budget Insurance too desperate for business - Refusing to cancel my contract

I have been trying to cancel my contract with Budget Insurance for about 3 months now but each time i contact them they put me through to a financial adviser who insist on advising me and offering me a better premium and asking me details of my new contract with a different provider. First month i reversed the premium with the bank and send an email to budget but instead Budget sent me an SMS that they will be debiting two days before the agreed date which is really an inconvenience. Month two indeed they debited two days before and when i call them i was told to call the bank as their processes take long. I called the bank they reverse the money again and issued the stop order. Month 3 Budget went against the stop order and debited my account again with a different reference number. This is very wrong and it costs money to place a stop order and a serious inconvenience to have money debited from my account two days before i get paid. This is ******* what Budget is doing. I cant go back and forth each month trying to reverse the debit order.
