Out-of-bundle rates

On Sunday 21-02-2016 at 02:00 I received an SMS saying that my 1GB data bundle has run out. I started using the internet that afternoon and purchased a once-off 1GB data bundle at 16:00. I received a message at 16:15 saying that I was nearing the end of my credit limit but didn't think anything of it as I had just bought a data bundle. Once I had finished the session, I received a SMS at 21:07 saying that my 1 GB data bundle has run out.<br> I went onto my account on Monday to see a bill for R3500!!! <br> I have a R100 credit limit on my account and I hadn't been informed that the 1GB I had purchased had run out until 21:00. I phoned the call centre on 22-02-2016 and was informed that unless I log in and log out, the data bundle wouldn't have been loaded and I would be browsing on out-of-bundle rates for most of the session! I thought at least I would've been blocked once my credit limit was reached or that the session would've used the funds I had available in the data bundle.<br> I was blocked today (2 days after I had already exceeded my R100 credit limit). <br> Endless struggles with this network who advertise the cheapest rates but will definitely find other ways to get their moneys' wort
