Hi there,
We use a mix of inhouse and outsourced support to give a true 24/7/365 support desk, however our sales team is not 24/7/365 they are more like 12/7/365 so to base your conclusion on sales reply time is incorrect.

I know of many other companies that are the same and I think this would be true in a lot more cases than you may think, so again the only true way to test out a companies support reply time is to test out their support.
