You tried reaching through the 'Chat With Us' Button on the support site https://amazingcharts.com/acsupport/ and got no response? Has always worked for me during regular business hours. Alternately I call the support number (866) 382-5932 and select “1” for Support I do this on the weekends, left a message and always have gotten a call back within an hour or so.
Of course haven't called in probably 6 months so ? maybe things have changed.
