Vodacom Strikes Again

We have 9 different contracts with Vodacom and pay our monthly bill without hesitation. Yet we are experiencing a problem with their billing department for the last 4 months.<br> We are billed for additional data usages on the number ***. We queried this bill as the operator of the phone was in hospital most of this time and could barely use her phone. Vodacom confirmed that the billing was correct and we paid the bill. <br> Last month I submitted a formal request as the data usage was again R1500 and Vodacom informed the operator that it was due to the use of WeChat and Gdrive. These weren't even installed on that phone, yet once again we paid the bill.<br> We went on the Vodacom website to look at the billing on the 9th of March 2015 and saw that again the data usage that Vodacom is billing is R2700.00. We called Vodacom and requested a full Forensic audit on this billing as we have been paying for data not used for 4 months. We requested that they do not call the operator of the phone but me or my husband as the contracts is in my husband's name. Yet they did not even do that.
