The Outside Lighting Specialist Ltd review for Google & YouTube

So for 18 month this app performed really well. impressions were decent and conversions were running at good levels. but then we dropped from average 80k impressions a month to 4k a month and the last 10 days zero. Cant get hold of google to resolve. It wont let me delete the campaign so I cant start a new one. you cant pause it and start a new one. all become a pointless exercise and waste of time.
