Lowe's Credit

I wanted to take advantage of the 6 months interest free promotion by using my Lowe's Credit card but was declined. The cashier called to see if my credit could be extended but was refused. When I got home I called their credit department and they said I hadn't used the card in awhile so the account had been frozen. I don't appreciate the humiliation of having held up a check-out line like I were a dead beat who doesn't pay their bills. I suggest that in the future Lowes send notices to customers that haven't been in for awhile to let them know that they don't want their business. This will save both the customer and Lowes precious time.
