Hey Karlo_Lugomer!
Sorry to hear about your issue.
I just verified your account and found that you were warned several times for selling forbidden items, such as forbidden Gift Cards.
You were also suspended for 30 days before, because of this and since you did not listen to the warnings, your account was suspended again, but this time permanently 
After the warnings, you should have verified the authorized non-gaming gift cards on Gameflip Help:
I really wish I could help you out, but you were warned too many times.
God speed!
