Vodacom is *****ing data

I have loaded 20 gigabytes in the last two days and still get a notice that I have no data to connect on my WiFi. It is apparent that there is a problem but this is ridiculous. This means that I have lost R1000 worth of data without having updated any computer software or applications. The problem has not yet been resolved. Internet connectivity is pathetic and therefor I will be moving service providers.
