Combidesk for Email Marketing

I wrote the below on Wednesday...here it is Friday evening and still no response!

I have both retail and wholesale customers and tags associated with both. However, before I purchased this app, they assured me this would integrate when connecting to Constant Contact...well it doesn't. I have sent three messages to these folks and it always states they are away and will contact me tomorrow. Tomorrow always comes and goes!!!!!!! I have yet to see how this app does anything different or in addition to the plane constant contact connection. Would love to hear from these folks
