Airtime credit disappearing no proof shown

It is now the third time that airtime disappears from my account. I have taken this matter up with Menlyn service center twice already and both times they only stated that the airtime was used but can not produce any proof of such charges. On the third time I thought it best to go to a different shop...Brooklynn this time. One of the shop attendance was very helpful but was shut down by customer service when she requested an itemised bill so that she could prove where the money went to. IT HAS GOTTEN SO BAD THAT EVEN THE VODACOM STAFF LEFT ARE SPEECHLESS!!!<br> Secondly, the app recommended by Vodacom to check on your airtime and data usage is inaccurate and has give faulty readings time and again. Even the *111# account info has given me different balances when requested seconds after each other.<br> <br> Just another case of a large powerful company bullying it's clients into spending more for less.
