Multifeed Google Shopping Feed

Told Multifeeds had relationship with another 3rd party shipping app and could tell Google that even though we use a 3rd party shipping app, that yes Google we have shipping set up but after 2+ months of back/forth emails with Taylor from Multifeeds app, nothing got accomplished and Google still only finding our 10 product test group on Limited basis. We lost a lot of sales during that time. Our last email to Taylor had well thought out detailed questions from our IT guy and Taylor's response was basically I read your emails and let me know if I can be of further assistance, excuse me he didn't even answer a single question. Too bad as we would have been a long time customer.
