NO COMMUNICATION!!! MULTIPLE DEBIT ORDERS

I have a contract with Netstar via First for Women. I wanted to move insurances because my premium was a little too high, my insurance was changed but never cancelled. Netstar then **********ly tried to debit my account TWICE in one month resulting in more than R250.00 of bank charges WITHOUT ANY COMMUNICATION or warning. Had they communicated effectively they would have gotten a suitable debit order date but they debited my account on the 2ND AND 16TH respectively...
