Santander Bank US Credit Card Complaint

Santander Bank US Credit card department,

Unsolicited issuance of credit card Texas

I received a credit card with a $10000.00 line of credit from Santander Bank. I did not apply or ask for this card, and have no financial relationship with Santander. I have now spoken to three people at this company, and thus far no one has been able to tell me they have closed this card. They have personal information about me that I did not provide to them, like my social security number, date of birth, and address. I want them to 1 ) tell me how this card request was made and how they received all my personal information, and 2 ) assure me that this account has been closed.
