Amazon UK account deactivated with no help

We have been selling on Amazon for almost 5 years. We have provided all the documents necessary to Amazon however for over 8 weeks now our Amazon uk account remains deactivated based on ID verification grounds. We attended a video call which was rejected despite showing valid ID and we have sent over loads of offical documents.

We are making absolutely no progress with getting our account reactivated and we need urgent help from senior leadership at amazon as this is dramatically affecting our business. What are the next steps.
