Question about subscription and daily rates

So, I recently took that 3 months for 30$ offer. When I signed up for it, it clearly stated that the next billing will be in June, if I don't cancel. I checked the status of my subscription today, it does say SuperGrok active, but says next billig is in April. Has anyone been billed extra during the 3 month period? Are we getting fleeced?

Secondly, the reason why I checked for the SuperGrok is that , today, while fooling around with the image gen , it told me I hit my rate limit after a few dozen images and I should try later or get SuperGrok (wtf?) Have they lowered the rates again? I can only imagine one can barely do a few 30 sec vids per day if so
