I cancelled my gym membership at OFJCC over 3 years ago. Now they are texting me once a week to get me to rejoin. I have requested three times that they stop with the spam texts but the texts keep coming. Crazy, crazy behavior for a gym. If someone needs a gym membership, they'll find you. Has anyone ever responded positively to a spam text from a gym? Hard to imagine so.
