Help device unlock over 2 weeks waiting.

Over 2 weeks ago I wanted to unlock my phone.  I attempted to do so via phone itself device unlock.  It told me I needed to payoff my phone.  I did so and tryed again but it gave error to reboot my phone and try again.  I did so but still same error.  I waiting about a week and kept trying daily but still same error.  I called in last Friday and support told me that its unlocked and that they will send the signal again and to try again in 24 to 72 hours.  I tried after 72 hours and every day since and still same issue.  I called again today and was told exact same thing.  My flight is coming up in a week and I need this phone unlocked to use international sims in it.  HELP.
