Double Debit not reversed

Vodacom promised that double debited accounts will be rectified by the close of business yesterday, Unfortunately this didn't happen with my accounts. I decided to call Vodacom this morning to check how far is the process of refunding me, only to find out that my account is on positive and they didn't reverse my money as they promised. Then the lady asked me if I want money, dam yes I want my money. My other debits orders bounced because of this. I asked the lady what will happen with the bank charges one incurred because of this and she said she doesn't know and she didn't know about the SMS Vodacom sent about refunding customers. She logged an incident for me with ref: S3-GJD11-18N41. My question is if I didn't call Vodacom meaning they were not going to refund me as promised? You also promised to bay bank charges, are you going to stick to you promise or not? Please resolve this immediately.
