I sent 9 packages FBA via ups to multiple destinations. 8 of them have been delivered. 

However one of them got lost at ups Tamworth they ups have acknowledged this.

For the life of me I can’t get an help from seller support. They have investigated after I provided all the documentation they requested and replied that they could not find it.

Well as stated it never got there in the first place so just a pointless exercise. All I want to know is how do I claim for my losses that ups have acknowledged. I can’t get Amazon to listen 

They repeatedly request documentation that they already have
