Missing data and airtime

Last night I loaded my phone with 1 GB data and R55 airtime (just before 6pm). I was unable browse the web or go onto Facebook as nothing would open or load, so I gave up. Besides sending my hubby a one sentence whatsapp I didn't use my phone. Less than the norm.<br> <br> Generally I load my phone with 1 GB data for the month and I'm able to go onto FB, whatsapp, play games, google, running apps with GPS etc without any problem.<br> <br> This morning when I woke up I saw I had an sms from vodacom on my phone that said my data was almost depleted. I immediately checked my balance and my phone showed 0 GB and R0 in my account.<br> <br> I phoned the call centre and they simply said that I used up all my data. Sending one whatsapp msg is not using up 1 GB of data and all my money. And as I read the complaints on here and all over the net this seems to be a general problem with Vodacom? They just tell people you left an app open or something to that extend at that is utter bull*****. Why all of a sudden people who never had a problem with there data has data disappearing overnight. Seems like some of our suppliers have just become as disastrous as our goverment, *****ing to make them richer.<br>
