Mtn *****ing data

I'm on a data package where I get 135Gig in total monthly. I recently noticed my data allocated for February was 120gig short by 15 gig. I called the customer care to enquire and I was told the 15gig is routed for streaming services on showmax. I never requested for this nor do I even use Showmax. I'm going to 2 weeks now trying to get assistance and my data allocated. I have reached out on Twitter but the services is horrible and perfomative. They asked me to dm my numbers and 2 weeks later nothing. Customer care is worse they keep opening service request which gets closed cause its supposedly opened in the wrong Dept, I've had supervisors who were supposed to call me and never did. I'm truly horrified mtn is basically *****ing from me, I don't even know how long they have been doing this. It never occurred to me that they can just start giving me less data I saw the 120 gig by chance. They had the audacity to increase my package price for the 2nd time within a space of like 6 months whereas they are *****ing my data. So how does this work price increase twice already and I haven't reached my 24month contract mark but on the side they ***** from us cause if they switch some of my data to streaming without my consent and I don't use that streaming service I'm basically loosing this data.. Still paying for it.. Paying even more now after the increase but I'm not getting what I'm paying for?? Horrible horrible service I'm cancelling as soon as the contract ends this year. The fact that I have to now check every month when data comes... And it probably won't be correct seeing that no one is helping me.
