Momentum Multiply continues to send communications after midnight in spite of several requests to stop

The Multiply Money function of Momentum keeps sending me communication, mostly text messages, between midnight and 5AM in the morning. I have requested several times to not receive these messages outside of business hours, but they keep sending them late at night, which often wakes me up. Momentum Multiply supposedly want its clients to live a healthy lifestyle with health rewards based on healthy living indicators. And yet they are not concerned about sending messages late at night which interferes with my sleep and are therefore detrimental to my health!
