TD Bank US Holding Company Credit Card Complaint

TD Bank US Holding Company Credit card department,

Credit card protection / Debt protection Florida

On - -, 2016 at - I was solicited to open a credit card account at Nordstrom Department Store . The account was opened and my purchases of $3400.00 were approved. On - -, 2016 around - I checked my credit report. To my dismay I discovered my credit score dropped drastically. My newly opened Nordstrom account is 244 % or $2400.00 over the credit limit. How can I be approved for this purchase and my credit damaged by opening a Nordstom account and using it without any knowledge of my credit limit?
