Integrating Square

Has anyone had a successful experience integrating their Square with their Quickbooks? I have downloaded the integration app but have questions about my products not being carried over. Square tells me they cant help me because it's a QuickBooks integration and Quickbooks tells me to contact Square. The process overall seems like it should be simple but I also feel like there is no support? Any advice or tips on how to talk to a person?. Please not a link to the how-to video that I've watched a hundred times haha. TIA
