Query: Too Short/ Me or the Ball

I purchased the ball chair with the 55 cm ball, the only size I found available through Amazon. It was advertised to fit someone 5' to someone 5'11". Being 5'2" I cannot reach my standard office deskwhen sitting in my new chair. I was told I look like a munchkin behind my desk. It seems unreasonable to hae to purchase another $30.00 ball
