Unlimited Issues

So I signed up tor Mobile X as a part of the their Black Friday, where the unlimited plan was truly unlimited. It seems like it might be 200gb, according to the app, but that is the issue I am concerned with right now. The first month I used about 74 GB with no issues. This month, I got to about 50 GB and seems to have throttled me. I searched the issue on here and reached out to customer support. Similar to what I read, they did something on the back end and asked me to reset my phone. Speed issue fixed. My concern is, now in the app, it lists that a free top up of 4GB was added to my account. So it looks like my problem of being throttled even though I have 150GB of high speed data remaining, per the app, was not fixed. I was just given more data? Is this something I am expected to do every month when I run into this issue? Can anyone with MobileX or with experience with this shed some light?
