I have been trying for 2 weeks to get our issue resolved with "customer support". We had several individual accounts/fax lines combined into a single account, keeping all the numbers the same. Now when one of our users try to send a fax via email, we get a return message that there are too many mailboxes and to log in to the account you are not using and delete your email address there. It seems like their system is still seeing the info from the old accounts and confusing it with the new account. Every call or chat to support always starts back at square one, describing the problem, sending screen shots, etc. and getting no where.
