You probably received a random text, not having contacted their company. Right? Your phone number was probably purchased from a collector. They will invite you to a caring call "Hi (you) it's xxx, there are some new Casting Calls so I want you to attend a Virtual Open Call tomorrow. Can you do 11am, 1pm or 3pm ET. Which one?" But, it's not a casting call - is a sales call for their PAID service, which is a scam. Legitimate casting companies DO NOT charge their actors to be included in their databases. My best advice to you is to block their number immediately - because they will text again, and again, and again... {Barf}
Do NOT give these people your money! Check their reviews! See some that I checked below -especially the Better Business Bureau. They've only been registered since 2019 and have had LOADS of complaints!
