Hi @Rafaaaaa_1303,
If you re-link the account back to the original EA Account without connecting it with a different EA account it should restore your progress. Linking it with a different EA Account may prevent that from working, though.
I think it would be best to get in touch with the EA Help team so they can take a look at the account from their side. You can find more details on how to create a case with them at the EA Help website. You can also speak with them over Facebook or Twitter instead.
