Just did a little web research on the Intrust Arena after so many complaints.

The arena is owned by Sedgwick County. It is managed by something called SMS Group. Intrust bank must have bought the naming rights.

All those nasty calls to some little secretary at the bank were probably useless. Needed to call SMS Group or the County Manager or commissioners. I assume the event staff were wearing Intrust vests or Ts but were employees of SMS Group.
