How can I access our company account?

[Lisa Mathias]

A previous employee left our company. The subscription for this is processed through a group GMAIL address, not an individual address. 

I am trying to log in with our username and password, and it keeps saying it is sending a code to this group email. It is not coming through. 

I need to get access to this account - how can I do this? Why is support so difficult to access?

For some reason, our invoice/receipt came through this group email address JUST fine this morning.
