They deduct airtime for all prepaid customers out of the blue. Systema take up to 12 hours to update evrytime. Very Bad service!!!

Twice in a row, every time I recharge I'm overcharged and told that the system takes 2 hours to update. What is wrong with yoi guys lately. I recommended you guys to so many people as I have been woth you guys long enough. I could not submit my assignment yesterday and my airtime took 12 hours to update correctly. Same thing is happening again today. You guys have the worst customer service ever. People that are rude and do not have correct answers to anything. Managers that attend meetings at 1am. Spoke to Lihle who asked me to call in an hour, then Akhona who told me if I by airtime I cannot do anthing with it but access internet as it is, the Isaac who didn't have a clue what he was doing and couldn't stop apologizing and a very very rude Mbali who said her manager was in a meeting at 1am. I lost marks on my assessment because of the bad and appalling service from you guys. Customer service keeps making excuses about systems that update everytime. I used to rely on you guys back then. I guess I will have to make alternatives and address this on every social media as possible, not to mention a YouTube video and records or the calls and post that on all social media platforms. I LOST MARKS because of the inconvenience of delayed and wrong deductions made everytime. Oh the guys at the call centre won't provide you with any reference numbers too. ***** and *****s.
