Military Financial - Take 2

I tried to post to my original post "Military Financial" but it takes me to a different thread, so here it goes again.

I have a "loan" out with Military Financial. I am in the state of Nevada and took out this loan here. My current outstanding balance is $1487.59. They took $483.00 out today and will take out $525.00 for the next 4 payday and then some change 2 more paydays. I am tired of being on the merry go round and want to stop this vicious cycle. I would like to know how do I go about getting them to stop taking it out of bank account. I can't afford to pay this any longer but want to pay it as I took out the loan but at an amount I can afford.

I am afraid to stop the withdrawals because I don't want them to call my CO.

Thanks for any help.
