Hi Ricardo,
Very sorry about this situation. Could you provide me your email I would be very happy to have a look.
Regarding the 30 days refunds policy, only the initial request is important. So if you did a request during the 30 days, it's ok, even if we answer days after, what we of course never do :)

For Google Analytics, more than 32 000 websites are using today WP Rocket, we never had any feedback regarding that.
Would be happy to have a look and helping you resolving this issue.
