How long does an APS case last?

I was recently accused of very random things from a client who I have constantly gotten onto for being extremely perverse. To top it all off, he never called the company and only brought things up when the company initiated conversations with him about other things. It's been over a week since the main nurse said she turned in the complaint to APS. I have called APS twice to see if anything has been received. (One week with no pay, I kinda want this to hurry.) The company has expressed constantly how they do not believe the accusations, but yet when I call to see if they have a case number or investigator number, they get aggravated and keep telling me APS is lying. They won't tell me if they have my information. From what I have read, Texas APS gets in contact withing 24 hours of receipt of report. This whole ordeal is causing me financial and physical harm. I can't eat, or I over eat. I am losing hair and I am depressed. I have proof that the accusations are false to any who are curious, but I can't shake the feeling that there is some bs going on that no one wants to confess to.
