TIRED OF MTN NONSENSE!!!!

I have been with MTN on prepaid for a couple of years and have never had issues with data until recently, I have been loading data on cellphone so that I can be access anything especially when I'm not home but my data vanishes these days on the 30th Aug I purchased a 6G+6G for R349 with the hope that it'll last me at least until midmonth or later in the month but the 6G that I can use during the day was finished in a matter of 1 day and half, with this problem I have been avoiding to spend too much time on social media or viewing videos as these proved to chowing my data like crazy recently. I have contacted MTN for a couple trying to figure out where the problem is with no LUCK!!! And one can actually assist me instead they just tell me that to switch off the background updates which I have for years now, no other solution, I am really GATFOL is their rude consultant treating me like I have no idea what I'm talking about...…Please MTN get your house in order someone is *****ing our data from your side!!!!!!
