Sellers keep changing the names/images of products I am selling

In the last month multiple sellers keep changing the names and images of products I am and have been selling for years or adding them in bulk (pack of 10 etc) or changing the size (85g to 320g) and it has caused unhappy customers thinking they are getting the wrong product.

Usually Amazon change my name back quite rapid when I suggest a name change due to someone changing it (nothing major just when they rearrange it) but recently they’re not accepting any of them. And after finding out which sellers are changing them, they’re all new sellers from the last month. Amazon have told me to report the ones I have found which doesn’t seem to have done anything (shock).

I found a few out as everyone else selling has the same price as me but there’s just one seller with a dearer price which correlates more to a pack of 10 than our price would.

I have too many listing to check their names and images everyday, and I am only realising something has changed when doing my inventory checks or someone has messaged to complain that their product is not like the picture.

Shouldn’t each seller of a product get a notification if the name or image has been changed? Especially if the quantity and brand name has changed.
