Overcharged and under-notified

I am done with this miserable excuse of a telephone network. I have a 2GB a month account with this horrible network. One thing is for sure, you never know how much data you have left! I checked on the myMTN app, on the [URL Removed] website and dialled *141# to check my data at the end of last month. It showed me that I still had 300MB remaining. I disabled my mobile data on the device from that day. Two days later I get an sms. The SMS said I have used up my last data. How? I disabled it. Anyway. My bill comes in and apparently I used 149MB over my data limit. That means I have to now pay R149 as out of bundle rates are ridiculous! Even after disabling the mobile data, data was still used! OR WAS IT? The 3 methods I used to check my balance and the notification sms were all inaccurate. In fact I already used 149 MB over when I initially checked my balance. Their website, app and *141# code are all wrong and the notify sms comes in 2 days later. This is the 3rd time this has happened to me. Just another reason why I will never recommend MTN. I will always bring them down. I WILL cancel my account with them at the precise moment I am able to and I will never consider them again. END...
