I know first hand that you a wrong. If you call and press 3 the number is removed (please allow 24 hours, 48 if its a weekend) NO PHONE NUMBER ARE RESOLD TO ANYONE!! And obviously your phone numbers are already known that's why you got a text!!
1. Not a scam
2. Your phone number will not be resold
3. Not a fraud either.
I happen to know first hand. You don't, you just make up lies. Sorry but your dead wrong about chjgroup.com
