I made a purchase from Amazon and it turned out to be Amazon Marketplace and it showed up as Amazon…
I then had to return this item and it shows as the Marketplace user
I think it would be good to reference both as the same thing for continuity, so you can easily pair the purchase and the refund.
Heya 
If you tap “Improve name, location or logo” on the transaction, you can request changes for the JSG Accessories transaction 
It might take a few days but hopefully Monzo will slap a logo on it and name it Amazon for you 
I suspect monzo don’t get the marketplace details so all they see it as a regular Amazon purchase.
Cheers @nexusmaniac I did that and it’s been updated now… I just think it could be identified by if the transaction starts with AMZ* then it should be Amazon or Amazon Marketplace
Interesting I just get this
Is that a purchase though? My issue is specific to a refund not coming back as the same as a pirchase
It is a purchase, i meant for some reason monzo don’t get the seller specifics during a purchase it looks like , so a refund wouldn’t automatically be linked, but I guess they could match the £ .
By your purchase does it have the same details as the refund like AMZ*JSG…
The purchase is AMZN Mktp…
But the point is a market place refund would work much like PayPal in that it would be prepended by AMZ* so could be easily identified as Amazon
