Unauthorized Debit to my account.

<p>I signed a Vodacom contract on 24th of May. My contract I signed stipulated that my debit is to come off my account ob the 1st of each month. Vodacom decided to debit my account on 25th of that month! I cancelled the unauthorized payment to Vodacom before it went off my account. Now Vodacom wants to Fine me and they say my account in arrears! My account would not be in arrears if they stuck to the original signed leagal contract! If this is the service I am going to receive from Vodacom I will be sending then a cancellation because of breach of contract! </p>
