JPMorgan Chase Credit Card Complaint

JPMorgan Chase Credit card department,

Credit line increase/decrease New York

My wife and I have a credit card with Chase ( in her name ) that had a $9000.00 credit limit. We own a few small businesses and we needed a credit card to make some purchases and gave the card someone in our office to make the purchases. We told them to use the card until it reaches its limit. We expected the card to stop working when it reached it limit at $9000.00. Instead $24000.00 in charges were approved. This is ok with us. We were investing into something and actually happy $24000.00 was approved. Why we are complaining is that Chase now is reporting my wife as 245 % over her credit limit. This is not right if the limit was $9000.00 the should not have allowed the account to reach $24000.00. We asked Chase to consider increasing the line to $24000.00 or more than $9000.00 and they have declined the application because this account is 245 % over its limit. Catch 22 basically if you can call it that. All we ask is they report the card as at its limit not 245 % over its limit. They refuse and now my wife 's credit score is poor when before it was good.
