I HAVE BEEN TRYING FOR 2 WEEKS TO GET A CALL BACK FOR A MAJOR ISSUE I AM HAVING WITH QB ONLINE

MESSED UP TRANSACTIONS DUE TO THE CONSTANT UPDATES THIS COMPANY DOES -ALSO ADMITTED BY THEIR OWN STAFF THAT CUSTOMERS ARE CALLING IN BY THE HUNDREDS. THIS COMPANY DOES NOT DELIVER THEIR PROMISE TO HELP THEIR CUSTOMERS AND CHARGE A PREMIUM.  SINCE 2013 I HAVE SPENT HUNDREDS OF HOURS FIXING PROBLEMS WITH THE RELATIONSHIP OF QB AND MAC OS. NEVER TO HAVE GOTTEN BETTER. NO ONE TO CALL AND NO REPLIES WHEN I ASK FOR CALL BACKS.
