Thank you Giovann_G,

I appreciate your referral to contacting Melio by phone. Melio does not answer their phone and their on-line support people say they have no phone support,  only on-line. 
What is the Melio / QB relationship? There are numerous posts in the QB support community forum about issues with Melio not making payments but debiting customers accounts. In essence keeping customer’s  money with no legal reason for doing so.
There are multiple on-line posts about similar issues that many customers experienced with Melio and complaints about Melio’s utter lack of customer support. The BBB site has scores of complaints about people not able to access funds that Melio has taken and not remitted or refunded. 
We chose Melio because of the integration with QB. It seemed that QB must have vetted Melio and was endorsing Melio because of the amount of integration permitted by QB. I would think that if a company  that has a track record of not remitting funds and has no practical customer service that would disqualify that co from being a QB integrated partner? 
The QB support community site has several issues documented and it appears that QB moderators only response is “keep trying to contact Melio”, as you responded to my post. I believe one moderator even advised a poster to contact Melio multiple times, after the poster mentioned they had sent a dozen emails and had not received a response from Melio. 
Is it QB’s policy to endorse and enable partner companies that under-perform, deceive, fail to communicate and by design do not have an effective customer response mechanism?
