Online be a pro - Lost boosts

[Mental_Ghost]

I recently just finished by 2nd season finally grinding hours into the game offline so i can play online with all my boost unlocked but the instant I was finished I lost everything.  Everything is locked again.  I was hoping if EA can help me fix this problem?  If they could reinburse by letting me have vouchers to unlock boost or something like that.  I tried to restart my seasons again but its totally not worth it because I already spent +20 hours at least into it.

I know deleting a certain file would make me loose my boost but i didnt touch anything from it.
