Refund my money back

I have reported a while back that vodacom has created a fiber *****ulent in my name, they have since closed the account as they said they will do. But to my surprised they have debited an amount of R630 in my account on the 15 of May. I have send an email regarding that on the 19 of May they send an email and they had confirmed that the money will be paid back in my account within 48 hours. However I have waited till date nothing has been paid in my account when I ask again I'm taken from pillar to post. I have send all the documents and proof but still I am not assisted. Vodacom I want my money to be paid as in today. As this is my money and I have worked hard for it you had no authority or justification to take it.
