Unauthorised charges

Got an MMS with my account, stating I activated a 3GB data bundle on my account. This is clearly false as I use the sim card in a feature phone. Tried contacting vodacom support via online chat only to be told, "Its only the account holder who can file a dispute".

Now I understand this, security and what not, but my mom is the account holder. I'm her son who physically uses the sim card. Surely you can look into why my account has a non-approved purchase thats tacked onto it.

I also think this isn't the first time, it may have gone off last month aswell. This is clearly NOT outlined in my contract. I specifically went with a top up contract so I can control my bill and not have any nasty surprises.

Also some more detail, we do not want to call you Vodacom, your consultants are overpowering and are hard to understand over the phone. We would like you to have robust online communication, as text is much easier to understand and misunderstandings will be avoided. This goes for all areas of your service, including cancellations.
