Vodacom incorrect billing

Good day<br> <br> I purchased a 1gb data bundle @R149 on Monday the 29th of February on number ***. <br> <br> My account was debited R298 and I was credited with 6gb of data.<br> <br> I have reported this anomaly 4 times now, once telephonically and 3 times via Twitter. Ref. No. is ***<br> <br> To date the status quo re my account remains unchanged.<br> <br> Why is this proving so challenging for you to rectify? <br> <br> Please advise as I'm losing patience!!<br> <br> Regards<br> Brent
