Debited for my cancel?ed Policy

I have being communicating back and forth between Liquid Capital who im told are my supposed brokers and FFW since the 3rd of March trying to get my comp insurance policy cancelled, after having no luck with Liquid capital to instruct FFW to xancelled i made my final call to FFW on the 15th of March at16.42 quite irate to cancel my policy, i finally spoke to the relationship manager on duty that day who helped me with cancellation & informed me my policy was cancelled and that no debits were going off my acc. To my dismay FFW denited my account for this month i am already insured with a new insurance company NOW I AM DOUBLE INSURED!!! I want this company to do a CANCELLATION & REVERSAL with IMMEDIATE effect, i am taking this up with the ombudsman as well, this is ludicrous!!!
