Debiting Accounts for rejected quote

I requested a quote had to give banking detail for this. Called back the very next day and said I am not going to take the policy it must be cancelled and so must the debit order. This NEVER happened my account was debited twice in the first month. Phoned again same story its cancelled again my account is debited. Phone requesting to speak to a manager who deals with this, only to be told numerous times managers are in a meeting will call you back......NEVER happens. In the mean time my account is still being debited. THIS IS RUBISH. Imagine if you do take a policy what drama it will be to claim..............................NO customer service in 1st for woman. This costs money every time I have to dispute the debit orders!!!!!!!!!!!!!!!!!!!!!!!!!!
