Is anyone else finding it near on impossible to be able to speak to someone at Seller Support?

Every time I try and call I get this - I have tried to call Account Health Support to complain but I get the same with them.

In the past month Amazon have lost two pallets of goods are refusing to compensate for 1 and low balling for the second, have said an Asin which we sell thousands of per month is incorrect and have classified it as an unexpected item, keeps changing booking times and address and finally claim that in order to sort another unexpected item delivery we need to set up a new ASIN for a product which is not even ours and suggest we sell it!

Is anyone else experiencing this as when I try to sort it out I am caught in a customer service feedback loop where no one either wants to help or knows what is going on?

Does anyone know who I can escalate to?

This is my first time using these forums as I am at my wits end!

For the first time ever today I'm experiencing a bug on only one specific item...

I select 'Send to Amazon' on the item... No prep need... Labelling done by seller... but when I go to input the unit count and then click 'Ready to Pack'

The blue Ready to Pack button does not appear... therefore I can't continue.

Anyone else experienced this?
