While you may have been a TRS at one point, that doesn’t necessarily mean you still deserve to be one. I know many sellers who used to be TRS, and are not anymore. Fiverr updated the levels system because they had too many TRS sellers who didn’t perform like top sellers. Those sellers – perhaps you were one of them – lost their coveted level because they couldn’t maintain the requirements.
As hard as it may be to hear this, Fiverr is extremely selective of those who hold the TRS level. No one deserves to be a TRS. Fiverr has sole discretion over who THEY feel should hold that rank. And the odds are, if you couldn’t maintain the level, Fiverr isn’t going to re-promote you just because you want that level. You proved that you couldn’t hold onto TRS, so that might play a part in Fiverr’s monthly selection process moving forward.
TRS is an honor, not a right.
