Does anyone have a telephone number for intuit accounts department to discuss an error on an invoice

I am having issues with an invoice from intuit that is wrong but cannot get in touch with anyone that can do anything about it for me. My account manager says she cant sort it out and numbers and emails Ive been provided with come back as they dont exist. has anyone else had this problem or does anyone have a working telephone number for intuits accounts department so that I can get this resolved?
