I've received the dreaded Prove your EU establishment email, threatening to suspend disbursements.

I have a few Amazon accounts, but this is for an Estonian business (via e-residency), that is established in Estonia and the UK, however i don't have a physical presence in the EU. I've been 100% compliant. I've paid all VAT via VAT services/AVASK and am registered for OSS.

However am I right in thinking I'm going to receive a duplicate VAT bill from Amazon? Will they stop disbursements and will this affect disbursements for my other businesses.

Are they offering instalment plans? Am I going to have to request VAT refunds from all countries and will AVASK sort this?

Any help/advice appreciated.
