Has any one borrowed from one of these fast cash loan companies?

I need 810 dollars to have 6 teeth surgically removed, before i have other work done that my insurance will pay for. i have been refused care credit by GE bank because when i turned 65 the state of Texas put an indef date for expiration on my state id card. a courtesy. i am afraid to apply to these other fast cash places because to apply i have to give them my bank account number and routing number, as well as social security number. i dont want to do this if im not assured i will get the loan first. does any one know a company that can be trusted? one that has been used a lot and gave no problems.?
