Frustrated!

Good day, the Vodacom app does not allow me to send a query, it keeps on saying that there are technical difficulties. Am left with this platform and no other choice. I recently called 111 to try and get information about my bill. I spoke to Thembela Futhiswa on the 31st of July 2018 at 11h51 to be precise. Please listen to this call, it was in Xhosa. When I inquired about my bill, on the 072 number in particular, as when I checked on the app, something did not make sense to me and I needed clarification. I remember someone whom I spoke to a while ago, saying that I had an open line on my data, so I needed to make sure if I was not using out of bundle data. The agent in question confirmed that I did not, I asked him to double check that for me and he did so, again he said no, I did not use those bundles. This past Saturday, I had to call again as this was bothering me and I spoke to Cindy, who actually called me at 14h15, she sang a different tune, that I had in fact used about R192 of out of bundle data. Vodacom, we need agents who have experience at this level and who are knowledgeable. I do not have a problem in paying my bill, I have done that for many years but some of us work on budgets so if someone makes such a mistakes in issuing the information, it gets costly and causes unnecessary frustrations. Please address. Thanks
