ITALY VAT claiming back VAT prepayment.

In 2020, I was still on PAN FBA with Avalara. I made Italy VAT prepayment.

In 2021 after BREXIT I stopped selling in Italy, and now I have over 2000 euro overpayment.

I was told by Avalara I have to wait at least 2 years to get it back. Now it is over 3 years.

Has anybody asked for refund from Italy for pre Brexit VAT prepayment?

Kind regards

Jack
