The SA-MP mods forum aren't liable for the donation process. We can't see wether you donate or not. We only can see if we recieved the credits. SA-MP mods forum keeps the full rights to change the donation rewards at any moment. We also can remove the donation rewards fully. There is no way for refunding and by donation you had to understand all of the above.
With other words, you donate and we remove all the donator rewards, we are allowed to do so. Also we hold the rights to remove the forum even after you donated.
