Hey there,
First of all welcome back :)
Unfortunately, Meepcraft does not do rank transfers, exceptions cannot be made.
Also, your screenshots do not provide enough evidence to show that you had VIP, because in no part of the screnshot is there a name of yours, in green (VIP Color)
What you can do is if you have access to the email of your Mojang account, or a copy of your receipt for the minecraft account, you can contact Mojang amd you can change your password there :)
I hope this helps and have a good day mate
