Thanks for your post about this R4MIN - sorry to hear you didn't get the boosted renown you'd expected.
To look into this, we'd need to take a closer look at your account. We're not able to do that from here on the forums, since we'd need to do some verification steps, for data protection reasons. As such, I'd like to invite you to get in touch with us by one of our direct channels, linked below.
Apologies that I can't help more directly, but I'm confident my colleagues on those teams can help with this
