BuyMirka.com review for Microsoft Channel

I really wanted this to work to reach a broader audience outside of Google Search but it has not been a good experience so far. I keep getting error messages trying to create a smart shopping campaign. Everything seems fine in the Microsoft Advertising side, not sure what is wrong, support is lacking. I sent a note for help to MS support but no response after 5 days. I have had a better experience with Google Shopping and it helps generate a lot of sales. I haven't given up yet but I can't say anything positive yet. I hope I can follow up with better news.
