Tru,
I am currently contracting right now as well. You probably have the initial paperwork that shows the hourly rate for the work. I would check through that paperwork to see if there is anything that looks like they can change the rate whenever they want. If you do not have something that says that then I would think that any change would be a new contract.
They may decide to cancel your contract rather than be forced to pay the old rate.

You may also want to find out if Kelly or the company you are at is the one that reduced the rate. If you are on good terms with the people at the company you are contracting to you might be able to find out from them.

I'm not the praying type, but you have my hopes for a good resolution to this.
