Charged more than 3x self imposed limit for data

Extra voluntary limit of R400 was set on Vodacom account over and above standard monthly rate.<br> Vodacom is meant to send 50%, 75% and 90% notification of nearing extra voluntary limit.<br> No 50% notification received.<br> 70% received at 11:52 on 6 July. At 13:00 account is soft locked and notified that account is now over R1,100 over the standard monthly rate. Only way to unlock is to raise limit. Limit raised 3 times to eventually reach R1,500 over numerous calls.<br> Data query lodged for excessive data use at three time points, which all just happen to be at a time phone is at home and on wifi. Please explain. Phone settings are set for updates to only update when on wifi.<br> Either i am a **** or Vodacom is?<br> What is the point of setting a voluntary limit if a state of the art Vodacom system is unable to provide timely notification. Wait - it is not in Vodacom's interest to provide this particular part of the service as they commit to because this way they are able to get you to use more data than you have stated you are willing or want to use and now you must pay! I have clearly shown that I am willing to pay for extra data if needed as per my past records, but over R1,000 for around 1gb!!!
