How long does Apple take to respond to activation lock request?

My other account "*****2@gmail.com" is locked, I have requested for unlocking by "https://iforgot.apple.com/unlock", I was informed that "we are reviewing your request to access your account, this process would take a day, Apple support can't shorted the review time"; but three days have passed, I still get no reply; please help
