You mention their website but you don't post the website address.
I GOOGLE Dallas Massage Center and found this
https://dallasmassagecenter.com/
Which gave me this:
Warning: Potential Security Risk Ahead
Firefox detected a potential security threat and did not continue to dallasmassagecenter.com. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

I did not go any farther than that warning page.
