Billing

Good evening, I want to bring under your attention the fact that I have been billed R5/min and this has been the case for quite a while now. I had R15 airtime (as a test) - made a phone call at 19:14 just to be disconnected at 03:48 seconds later. How in the world is it possible, If I make the same call from 8ta, then I could speak four times longer. Have a look at my number and I am sure you will be able to confirm what was said here.
