Citizens Equity First Credit Union review: small business account

I have had a small business account with Cefcu for about 5 years. My business is seasonal so I don't use the account for about 6 months out of the year. However, I am charged a $5 monthly service fee to keep my account open throughout the year. This just seems like a penalty to small businesses. Why does Cefcu not provide free business checking account? I am greatly disappointed in a company that takes my money for no services being used 6 months out of the year. I like their services mostly, but this makes no business sense to me. I guess that I will open a free business account with a bank next door. Thanks
