Neglect to inform and charge ******ionate rates

Vodacom neglected to inform me by sms that my data bundle has run out. I have made an effort to keep data low and stay in bundle rates this month. They did not inform me that my bundle was finished so that they can charge ******ionate rates. I'm beginning to think it is intentional. This is an absolute abuse of the consumer.<br> <br> Sincerely<br> Abused Consumer
