Vodacom *****s your airtime with out notifying you

As a pay as you go customer with vodacom for the last +- 15 years i find their service has become worse.<br> Vodacom makes it a priority to send sms's for knight shift every time you load airtime but when your data bundle expires that is never a priority! Only sometimes i don't get these sms's to say my data bundle is expired and then my remaining airtime gets taken with out me knowing.<br> I have spoken to the call center numerous times and i get told is that i must check my balances everyday.<br> This is vodacom's *********** pathetic service that i get!<br> Paying for services we don't get!!!
