Data and signal strength issue

Hi, I am repeatedly having this problem of my data being ****** and repeatedly Vodacom aka *****s keep telling me that I am the one that is not controlling my data use

This is the scenario (and it happened more than once) I have complained about this previously, but nothing is being done about it........

I buy a gig from Vodacom and not even an hour later my data balance shows zero. This is with no extra internet activity or sometimes even with my mobile data set to off. This is blatant *******. Like I said, I have complained about this before but nothing is being done about it, but I am not going to stop complaining about this because it is not right

My second issue - I have been complaining since 2012 about the signal strength within my area Bosmont (2093) however nothing has been done about it until today, what service is this where you do not deliver on anything but you find it in order to ***** from your clients

Can something for once be done about both my issues! Come on Vodacom you are better than this?
