No Feedback or Resolution

Over the past 2 months I have contacted Vodacom on 3 occasions to raise the concern of lost data. I was provided with 3 reference numbers, to my surprise i received 2 smses telling me my query is resolved and that i should download a data tracking app. This after explaining my frustration to the team and that I have been tracking my data for a month prior to contacting the team. This is complete inconvenience to me not to mention the financial impact on the data loss. I have never used this much data and something strange is going on. All i ask is for someone to investigate my query and rectify this asap.
