'******' data replaced

My monthly 3 Gigs of data were used up in 3 days this month - not by me. The <br> Vodacom store where I renewed my data contract were unable ( I'd say unwilling) to help in any way. They referred me to the call centre, which didn't fill me with hope.<br> <br> The call centre was predictably disinterested and even obstructive, arguing that if I had control of the SIM, no one else could have used my data. I insisted they logged a case. Although I didn't receive the promised reference number per sms, I had a call from a much more professional and helpful technical Vodacom person. He advised that I would have the missing data replaced and gave me some tips for securing it in future (such as setting a password for my wifi, even if I'm using it as mobile modem, and not wifi per se.) I was gobsmacked to be listened to, and have it remedied without a huge battle. Thanks, Vodacom, you turned me instantaneously from a resentful, frustrated customer into a satisfied one. Keep it up now.
