Technical issues galore!

Standard Bank mobile has been riddled with technical problems from the very start, and have since then not sorted this out. This started with advertised functionality, like itemized billing, not working on their website from the start. They seem to have decide to "solve" the problem by just removing the link on the website. Most annoying and most recently they have continued charging me for data at R0.49 per MB even though I paid them R149 for a R0.07 per MB data rate. Due to them continuing to charge me at the wrong rate, my inclusive value was completely depleted within about a day, and I was charged an additional R300+ for 700mb of data, in a single day, instead of the R49 I should have been charged. I have highlighted this issue to them, and have proved it to them using the information supp**** by support, but for 25 days now I have not received any solution or refund of airtime. They have now also charge my bank account for the incorrectly billed data, so I can only conclude that they cannot or will not resolve their own technical issues.
