Wd black ssd 2tb sn750 recognized as sn720 512

Hello I live in Mexico and buy 2 discs of this model directly from Amazon Mexico, I used one to install on a MacBook and all works, the other one I will use to mount an external thunderbolt 3 drive, but the enclosure, also purchased from Amazon MX, takes a month to arrive, when it arrives I use the other SSD and discover that it only gives 500 GB of Capacity, the box and the labels say that it is a 2TB SN750, but the system does not take it that way, I already tried it on Win 10 PC and other Macs, installing it internally and in an external box and everyone recognizes it as a 500 GB SN720. Amazon Mexico does not want to give me a guarantee. What I can do?
