Is she a beloved and highly paid tech exec who will have a ~200k+ salary waiting for her after a year away?

The majority of people here are Boeing, Navy, or hospital people; not very tech.

After 2 hours on the phone with their tech support, I've learned that I cannot download transactions from either my bank (Bank of America) or my credit card (CitiBank) which renders the software completely useless to me. 

@Will Gordon I've used basic answering services before and simply had a list of my vendors for them to call for each situation: plumber, heating tech, electrician, handy man, etc.
