tangkula review for Simprosys Google Shopping Feed

Really a bunch of problems, first of all, all the products reported errors, a total of five or six times to contact to solve the problem, and one after another more than three months to take a long time! Now, one-fifth of the products are always in PENDING status, which seriously affects our ad conversion results, and the technical and customer service support is always 24-48 hours to provide service! I am really fed up with this app!!!Please return all my money to me!
