ASIN suspended from Sponsored Ads


I have a product currently suspended from Sponsored Ads.

No reason given and I have had a case open with Seller Support since 29th July. Despite chasing this several times and promises that the case is being escalated, SC still have not given any response other than ‘we have a backlog’. I’m not really not sure what I can do now, or indeed why this ASIN is suspended. Has anyone had any similar experiences? Any little insights that might explain what is going on?
