I have similar experience. Only one payment late 2 years back, which was my first and only payment due to Kohls. I pay my balance off on time normally. Called Customer service and explained situation, and also that Kohl's is the only derogatory item on my credit report, but they would not change status. I have closed my account with Kohl's, and regret opening one with them in first place. I intend keeping minimum number of credit cards open, and will pass by store offers of credit for sure.
