Bell federal credit union?

[¥mmSÞèåkÑøÉmílmm¥]

I have this card that my grandmother gave me when i was younger and it has my name on it, and her name, and my account number. It's a savings account number and the only thing i can find about out about it is it's name is Bell Federal Credit Union, and it has a logo of a bunch of arrows inside a circle.

Is anyone familiar with Bell Credit Union? If so do you know the number for the office in Omaha Nebraska?
