account debitted after cancellation

I had an insurance policy through Regent with liquid capital, I was not attended to, I had a claim query and had to pay a excess amount which was not worth it for the damage. After recieving poor service, I cancelled in March.<br> I recieved cancellation confirmation.<br> I sent an email notifying the accounts people my account was debitted for April,<br> I was told it would be ammended and corrected and the Money returned into my account.<br> I have still not recieved my money back and account being debitted.<br>
