I am trying to track a removal request return. I can see that it has been actioned, and there is even a tracking number (beginning with UK) in the FBA inventory reports.

However, there is no way to track this number. It is not recognised by UPS or any other carrier. After various useless exchanges with Amazon customer "service", I was told that this tracking is for internal use only, and Amazon does not share access of this tracking. They would only tell me it is being processed.

Ridiculous!
