Metro PCS Android Unlock App FAILED

Hello support,
I think there is something going wrong with the Metro PCS Android Unlock App server.

I got back 2 orders as completed. I waited up to 4 hours then tried the unlock procedure and they both failed. Please verify if something is wrong. Hate to have to refund customers.

Order numbers:- 676936 (59A5331) and 673720 (5997BC1)

Thanks
