Our VAT number is up to date definitely conformed by EU VAT checking service as per standard EU link attached

ec.europa.eu/taxation_customs/vies/#/vat-validation

and the number is in line with templates being suggested by Amazon

sellercentral.amazon.co.uk/help/hub/reference/G28U9N22T3K2YJ9V

However - despite this the number is being rejected by Amazon set up - is there a reason to keep being rejected if number is 100% correct - and how to reach Customer support to get this sorted?

Thank you
