Telkom *****

I am very Telkom took my R228.00 airtime without my authorisation with monice data when I called they said they understand the problem is on their side and they will investigate the case. They sent me an SMS saying they have resolved the case. But still my airtime was not refunded I called and they said they will refund the airtime that I should not use the data. I did as they said but still today I have not seen my airtime I called again only to be told that they can't give me my airtime back. I need help I want my airtime
