Standard Bank update SMS's don't mean anything!!

At the beginning of May, I (thought I had) purchased 6GB of mobile data from Vodacom using the Standard Bank Internet Banking app on my phone. <br> <br> The reason why I THOUGHT the payment was successful is because I received SMS's from Standard Bank confirming the purchase amounts and stating my new account balance. <br> <br> I was sadly proven very wrong.<br> <br> Today, on enquiry, the Standard Bank call centre operator politely told me that I should have checked my statement because the SMS's aren't actually a true reflection of my account activity. Apparently, the SMS's are merely there to alert you that someone is using your card/account... Um...? The reason I don't check my statement is because I trust the SMS's! No one has ever told me otherwise! How can these SMS's not be reliable?! If they aren't reliable, what is the point? <br> <br> Vodacom has now billed me \out of bundle"rates for the entirety of May - over R5000 - almost 10x what I would have paid for the data bundles that I TRIED to buy and THOUGHT I HAD BOUGHT. Vodacom did not notify me until TODAY that I was being billed \""out of bundle\"" rates.<br> <br> I feel like both Vodacom and Standard Bank have taken advantage of my ignorance as a customer. :(<br> """
