****** debiting my account twice!!!!

Vodacom debited my account twice for December and hasnt reversed the one additional debit order. Absolute ****** trying to ***** your money because if you dont notice the double debit order they will just hold onto your money. This is now inconveniencing me as it has now thrown out all my other debit orders as there will be less money in the account for the other debits and now i probably have to call around using my airtime to be sent from pillar to post. Thanks vodacom u *********** *****s!!!!!
