SMS Notifications

I currently have a data contract for my router. Initially I used to receive notification when data was low. This stopped happening since July. The same time data started disappearing from numerous customers accounts. Apparently someone got the message. Suddenly from 28 September 2015, I have received over 28 SMSs... Sometimes 2 or 3 a day saying that I have less than 3mb left. Needless to say I have to log in to check my balance on the website (because the vodacom app on my phone doesn't work correctly). Funny though, because as at today I still have over 5GB available? So are the SMS they send even useful. I think not... It is like spam now. Vodacom needs to get someone that can actually manage their systems. Customer care always says sorry technicians are working on the website or app, or porthole. Get it right Vodacom. I have 3 contracts and 2 prepaids. Might have to start looking elsewhere, because obviously Vodacom doesn't care about their customers.
