Amazon Buy Shipping Royal Mail Account Linking - Unable to Add Tracked Shipping Methods

Hi All,

we've been unable to use our Royal Mail Account for Seller Fulfilled Prime because we can't purchased tracked shipping labels through Amazon Buy Shipping (non-tracked are available).

We've been told by Seller Seller Support and Royal Mail Business Support to contact Royal Mail's Amazon team through

royal.mail.amazon.in @ royalmail.com but they never respond.

This is also the email given in the Amazon Buy Shipping reference

Has anyone had a similar issues, or any luck contacting Royal Mail's Amazon team through royal.mail.amazon.in @ royalmail.com?

Thanks
