Cancellation still not done

I've been chatting to Channing Crowly since June regarding the cancellation of my home alarm. Channing confirmed cancellation but in July another payment was deducted and when following up with channing I was informed that money will be refunded to me. Another debit order was deducted from my account and still no refund... I've emailed channing again and have still not received any feedback.... I am not in SA and can only be reached via email... please can the alarm be cancelled effective 30 June and premiums deducted to date be refunded back to my account...
