Recently bought an iphone by amazon which was unlocked for any carrier, but the one used was t-mobile I already followed all the steps that the same request through itunes and I continue with my device locked to use other sim card, in case I need use a Brazilian operator. I can not be reached by T-mobile my email is xxxxxxxxxxxxxxxxxxxx I need the code to unlock IMEI

Your best bet is to return the phone to Amazon since it's not unlocked and Tmobile will
only unlock phones for Tmobile users.
This phone probably is part of Apple's 3rd party resellers flex policy which the phone is sold as unlocked but locks the phone to the first sim card
