Bill issues, again...

Good Day

I called Vodacom to query my bill. The amount was a couple of rands more and i wanted to know why. An international sms was credited and for some reason re-added the next month and one of my other accounts was also out. The representative said this is strange and that she would call me back the next day (sms was sent). To date no one has come in contact with me regarding this. Its very frustrating to have to check Voda all the time as this puts doubt in my mind about other stuff as well. They already increased my monthly bill just because they need more money for infrastructure. Like this is my problem?? This happend in April just after the 15% tax hike. The voda app is also useless as it gives the wrong info all the time and that's when it works... You usually get errors on it. I need this fixed or someone must call me to explain whats going on.
