missing content i can't get back

Missing content, even though I bought the deluxe upgrade. I have this license plate for two cars on which I have applied it already (an Infiniti Q60 and the Ferrari 488), but then I tried to buy it for a third car and it gave me an error saying "unavaible purchase, try later" or something like this, then the license plate disappeared for EVERY CAR (except the Q60 and the 488). And I paid 10 euros for this, nice. I talked to italian EA support three times but what they said is that I can't get this back because they can't help me and I can't even get a refund for the content I bought but I don't own anymore. Thank you EA.

They told me to repair my game, to update it, to try to restart origin and other stuff but it didn't work. Now, since I'm not interested in the other deluxe edition content, I just wasted my money because I can't get my content is lost.

(I apologize for my game being in italian but I'm italian, I should put it in english but idk how)

You can see in the screenshot that I have 12 license plates available for the Ferrari while just 11 for the Civic.

I just wish this is a bug and they will patch it out, but meh... We are talking about ghost games, doubt they even care
