Somehow linked to Marketplaces I don't sell on

I only sell on the UK marketplace, but a few months ago I noticed charges for DE and SP… After 5-6 messages to seller support to find out what the problem was, they eventually refunded me the charges after forcing me to register the company bank details on these marketplaces before they would investigate further.

Since then, I’m regularly receiving emails in German and Spanish, and all of my listings have “+2 marketplaces” next to them, indicating the possibility of listing on these marketplaces. It also means that my Seller Toolkit is giving me dozens of updates a day to tell me of price changes on these marketplaces too.

I queried this with Seller Support, as to how to remove these Marketplaces that I never wanted to sell on, and the first agent told me to log onto the marketplaces and close my account there. Obviously, I don’t have much faith in Seller Support and queried if this was the correct action, as I did not wish to mess something up and shut down my account completely. Turns out (you guessed it) that if I did this it would close my account in all marketplaces… They seem to think it’s not possible to de-register for a marketplace (that I never registered to sell on in the first place)

Does anyone know of a work around? Im sick and tired of these emails and my STK being filled up with notifications all the time.
