Tmobile Usa blocks devices

My two orders:
629837
629835
have completed with code: Iphoneunlock
But when I check on this site
http__www_t-mobile_com/verifyimei_aspx
It said that
Your device is blocked and will not work on T-Mobile’s network.

Could you please check why? (I asked for Recheck in ifoneunlock_com too)

One point is my device is not active yet (because I’m selling device) but I haven’t seen this blocking before

Thanks
p.s
My userid is: AZShop_US
