Debiting bank account when policy is cancelled

I received a letter that my policy was cancelled on the 19th June for end of June 2015. This company continued to debit my bank account even after i received the letter. I yook the matter up with the Broker eho followed up with Kagiso. I also sent an email to kagiso and he just never gets back to me. Its now a week that i have been eaiting for them to refund me without any feedback. Will mever consider taking a policy with Admed again. Very dissappoited with service.
