Pending account verification

The system have triggered a verification of my account information, even though my information has not changed. Consequently my selling privileges have been suspended.

I have been requested to provide again all my information personal and company, which I did. During my chat with support and emails with seller verification I have been told that I have provided all required information and that I have to wait for the verification process (first for 5 working days, and then with no commitment on how long the verification process will take).

My last chat with the support team I have been advised that I could escalate to (managingdirector@amazon.co.uk). I would like to know if this is necessary or should I wait more for the verification process knowing that I have stranded inventory in my seller account and much more inventory pending at my warehouse.
