I completely agree with you and other users on this thread.  Melio has absolutely abysmal customer service, dare I say no customer service at all.  I have been trying to reach someone at Melio  for weeks regarding a payment.  Their two customer service numbers that Intuit/QuickBooks gave me only tell you to log onto their website and "chat" with an associate. But once you follow the steps, suddenly there are no associates available.  It is crazy that QuickBooks allows a 3rd party vendor to not have a customer service facet to their business.
