Stay way from AT&T Office At Hand ---- far, far away

If I could rate AT&T Office at Hand less than zero I would. Billing is a mystery. Forget about trying to manage your account through an online login. It took me WEEKS to even get one setup, and that required assistance from my original sales rep (whom we've never met.) Since we've been using this service, I get 2 emails a week from other AT&T sales reps trying to sell me the same service I've already bought. As an administrator and a user of the services we get from AT&T, I have to keep up with FOUR logins: My user login for my softphone My admin login to manage other softphone users My login to pay for our internet service to our office location My login to see invoices and manage the billing for Office at Hand -- THIS LOGIN HAS NEVER WORKED ONE SINGLE TIME When I've tried to call the number listed on my paper bill, I get routed to non-English speakers who have hung up on me 3 times. It would be convenient if I could set up automatic billing for Office At Hand online, but since the login never works, that's impossible. Also, now I don't trust anything about the system to give them my credit card or a bank routing number. My next bill is due in less than 10 days, and I still don't have the paper bill in my hand to reference the (always changing) amount so I can mail the check-in time. STAY AWAY. THIS SERVICE IS EXTREMELY DIFFICULT TO MANAGE. Sign up for Office At Hand if you want to waste HOURS doing simple tasks....like trying to pay your bill.
