"Increased premium"

So I took the R595 package with Rain on the 19th February 2024. End of March they started debiting R75 more on my account. Today i call to check why is that as now its the 3rd month i'm paying the R75 more. The consultant starts telling me that they have increased their packages and they sent me an sms to notify me of the increase and i tell her that i have never received any communication on my phone or via email hence i'm calling to find out why are they debiting R670 instead of R595. Then she changes her statement by saying i have leveled up on the x2 sim cards that i got when i signed up. I hardly use those sim cards and also i don't even know how to level up so how could that have happed because i have never leveled up on anything, even when i check my profile it doesn't show that there's any level up. Please look into this as i cannot be paying for something that i did not activate !!!
