Melio entries in my QBO account

I too, like so many others, noticed Melio entries in my QBO online account as I began to do my end of month reports and called Customer Service to ask what the "Melio amount change" was on my accounts.

The Customer Service Rep, Alan O. insisted he couldn't even talk to me unless we did a screen share to "give him more information." So, at last, I granted his wish to look at my screen. And like others, the audit trail indicated that I had edited the accounts and made the entries even though some showed they had been edited in the late hours of the night when I would have never been in my office! He kept trying to convince me that I had signed up and linked the app Melio. Transactions on invoices and bills were altered and ultimately my financials in the chart of accounts. The app counter-adjusted amounts affecting my chart of accounts. I KNOW I did not sign up, agree to, download, or link this app. I also keep all of my emails and searched my emails to see if there was any information on this app. The only email referencing this app was when I disconnected it this morning from my QBO. Of course when I asked what the resolution would be in fixing the transactions that had been affected, the typical response was, "well...we can see that you connected this app..." which translates to QuickBooks NEVER takes responsibility for anything that has a glitch or goes wrong with their system. I have spent my morning hours correcting transactions and I'm hoping that I found them all!
