I asked for this a long time ago, and it's seriously grinding on my nerves when i read about people getting these crazy-ass billing surprises.
I had mine too [on MTN] , main reason was MTN could not tell me -IN ADVANCE- what's going on, if i didn't lock my simcard away it would've done serious damage to my finances..
Fact of the matter is, Vodacom and MTN needs to get their crappy contract systems sorted out. For the amount of money they are making, it's unacceptable how we can't manage,monitor and control our accounts properly.
I want to :
1. Set my own limits. I don't want to phone someone every time. If a banking site can do this in TWO CLICKS, then my goodness a telecoms company should be able to do it 10 times better. There's no excuse for not having this.
2. I want alerts whenever i want them based on my own criteria. If i want to be notified every 100MBs then charge me , just make the service...i pay for exactly this to protect my credit card account [which have much smaller limits on them than what my Vodacom/MTN accounts can go into......!] .
3. MTN/Vodacom can at least -try- to get a proper analysis system on their end. I mean come on , if a BANK can pick up i'm doing an "abnormal" transaction within minutes and phone me , why can't Telecoms? The fact that i read people who have a regular R500 p/month bill suddenly getting a R10k-R20k bill...what the hell? At a bank this would've sent red flags off all over the show BEFORE the customer even knew about it....
4. Real time , real time , real time...contracts are currently the worst possible option if you want to control and manage your data usage. It can ruin you, you can't see anything in real time, that's also why Voda/MTN can't provide proper mechanism to monitor your usage -NOW- [not 3 days later when the damage is done, NOW...] .
Anyway i've experienced both Voda and MTNs systems, had my fair share of billing errors on both sides...so i know BOTH are equally bad with this.
