Why would you close them after taking the inc's and actually getting the accounts? Any open credit will help your util and in time you can negotiate better rates etc.
Wouldn't it make more sense to keep them in the "sock drawer" and dust them off once every 6 months, buy a cup of coffee, then pif and put em back away?
Your still voting with your business and taking advantage of the boost to the CR.
I could be wrong, but it seems to me that you may be reacting emotionally rather than logically to the denial.
I'm not opposed to closing an account if it's not doing you any good, but leaving them open and idle may logically do you more good than closing them to make a "statement".
Something to think about.
Just my 2 pennies worth.
