High invoice each month due to poor systems

To Whom it may concern...<br> <br> To cut a long story short - this is now the second month in a row this happens. <br> On the 2 of September I received an sms telling me that my Vodacom data bundle have been depleted. Phoning the call center and asking how this is possible seeing that the month has just started - I was told that I must phone back in a few days time seeing that accounts etc. are finalized on the 4th of each month. The call center agent did put me at ease and said that I still have data available and that this is a Vodacom problem.<br> The 5th of September I phone again - now sitting with a bill of R1200 I phoned back to ask why this is so. After 4x Calls back to Vodacom, 3 service request later, 21 days down the line a technician did phone me back. After explaining my frustration with this technician very calmly for about 30sec - she literally hung up the phone. I have not yet received a call back:<br> Summary: I use my vodacom app, vodacom website and sms portal to keep up to date with my data usage. Not one of these 3x platforms are ever correct and sometimes delayed by more than a week. This makes monitoring impossible and leads to SKY HIGH account bills month end.
