Shop is unsafe?

So, here i am preordering the Diablo 4 beta. I have not logged into the shop for a long time. I log in with an SMS code i received from the site on my phone with the number they take from my account information, and ordered Diablo, and not 2 minutes later i receive another SMS from different number, being +46 76-396 79 43.

That SMS tells me my account has been locked, Visit Account Management to unlock it.

Is this legit? I am still logged in, i didn’t enter my phone number, it showed on the site with all XXX and then the last two digits so i knew that was the correct number , and i can still post this without taking any action.

How is this possible and is the message legit?
