Candle Monster review for Rontar Ad Exchange: Free Ads

Saw my own ad today on a webpage after using this for more than a year. My ad had a broken header so it wasn't showing my logo, it was showing old product images from longer than 8 months ago which were removed from the shop way back then when the new ones were put in. They had no idea something was wrong. I'm guessing all their customers are probably affected. I've spent around $1,966 on advertising through them which I reckon I just wasted. They offered me a $25 credit as the remedy for 8 months of showing old product images that weren't converting instead of the new ones I'd evolved massively. Are you joking? Shopify what the hell I expect a certain standard in here.
