Cap Use UNTRACKABLE!

I purchased a 50GB LTE-A deal with Mweb, and was happy with the sign-up and delivery and the speeds were great. However, I am HIGHLY ANNOYED with the experience I received over the last 24 hours. I spent the better part of last night and this morning trying to figure out why I can't connect to the internet. Called Mweb this morning, spent 20 minutes on the line only for the guy to tell me to reset my router and wait an hour. Did that. Still not working. Called again, spoke to a different guy who told me that my cap was all used up. Uhm - - firstly, I'm extra annoyed because as a new capped user I was quite anal about checking up on my use. And even today, it reads as being 41% used. The guy over the phone then says that the data tracking is not working. HOW does that help a CAPPED USER who is supposed to monitor their use? Why is there nothing on the website stating that there is an issue with the tracking? Why was there no SMS notification sent regarding this issue? Why was I not sent timely SMSs to inform me that I was at 50% use and 30% use etc? I've been going relatively insane with the internet use under the assumption my data was all okay, only to be sold a booster buy the guy to add on to my account, which I will now be billed for.

I left Mweb back in 2014 because of a poor experience and having returned in 2018 this new experience leaves a sour taste in my mouth. Data use tracking is CRITICAL for a capped user, and for Mweb to not inform of a broken service is disappointing and I do expect some sort of compensation for this.
