Corporate loyalty programs that require customers to surrender their personal phone numbers and then repeatedly harass them are unacceptable.

“If it takes me giving you my cell phone number to be a member of your loyalty program, then I am out. So then when you say, "No, I'm going to pass on your loyalty program." It says, "Oh, so you don't want the free rewards." Like, I just don't want you attacking my phone non-stop.”
