I used the trainer to get money to level up my cars, but went back online to figure out I still have 999m, as i couldn’t find any other way to fix it. So I am searching for a way to lose money quickly

I take it you didn’t read the trainer’s instructions fully in the Info tab of the trainer, which you’re forced to read before you can use the trainer for the first time?
