Bill - Data usage

<p>An sms was found on my one cellphone ********** 229 on the 6th of June 2017 - the 29th of May 2017 an sms was send to say an high usage was detected on data use R4251.71.There is a R50-00 limit that was placed on the phone because the nr is in my daughter's phone. She is only 12 years old. I immediately phoned Vodacom on the nr ********** . An agent assisted me. She could not find the sms on the system. She transferred me (just listen to the voice recordings) I was very upset. An person higher up spoke to me and said she can not find an indication and that I only owed R377.00 - I paid that amount over with eft. This morning I received my bill. An lovely R4233.94 for data usage. I phoned again Vodacom - Call centre agent seems not to care - I referred to my phone call on the 6th of June - please listen to the recording - no he will refer it to data. I am fedup - why did I place a R50-00 limit on the phone. Why phone on the 6th and Vodacom told me ignore the sms - must be sended to the wrong nr. And what do I get? A hudge shock, It is not acceptable. I am not happy the way Vodacom treated me. I can not see why they did not block the phone after R50-00 was used - and when I phoned they told me it is not on the system - I must ignore the message on sms. Again I ask the same question. 1) Listen to the two voice recodrings of both Vodacom agents, and why did they not block the data usage after the limit was reached? I want answers and I want a sulotion - I am very very upset. </p>
