Amazon force-merged ASIN’s without asking and stranded 6000 units, now what?

We have a HUGE issue.
We had product ASIN B001 and Amazon merged it with another similar item as a variation on another ASIN: B002 but the problem is the inventory from the other merged SKU is now “stranded” due to this merge and now almost 6000 units is sitting not able to sell and Amazon wants us to pay ENORMOUS removal fees to get it back. $4.40 is Amazon’s cost PER item on average and the item value is only $15.
The only option they gave me is to create a removal order, but this will cost us roughly $4.50*5941 per item, which is a total cost of $26,734.50 for JUST for shipping. This is NOT fair and I am seriously considering a consult for some legal counsel but first wanted to ask if anyone had any luck re-mapping stranded inventory to it’s merged SKU? Or any other idea on what to tell Amazon on what they should do to resolve this?

Seller support is a bunch of automated crap. All the names on supper emails seem nearly fake and nobody really knows how to fix complicated issues like this and we are facing enormous losses due to this.

Hope someone has fixed an issue like this,. or advice? Or I guess well be forced to toss out a massive amount of value, because paying $26K is absurd at this point since this product is an expiring product and we don’t know the shelf life remaining because there is literally NO way to tell in the Amazon system.

You can’t even make this up. Amazon is so insane! 🙁
