My Vodacom App:Misleading Clients

I have installed this app and it is a waste of time and money.It does not work,giving wrong info etc etc.After visting a Client Service centre,their answer..\No sir,just uninstall the app and install again and it will work\"After 3 sessions...almost 100mb further which i had to pay for...still no luck.Then Vodacom still advise prepaid clients to use this app without notifying them there is a problem.Totally unacceptable!When will this be fixed Vodacom?Please advise your clients."
