Empty promises and Promotions to Trap customers

Empty promises and promotions to trap customers into renewing their subscription. I received a promotional email (have the email as evidence) if I renew my subscription I will get another month free, 2 months for the price of 1 and to renew before 31 July 2025. I renewed my subscription and Lo and Behold, have not received my free month but definitely getting reminders every day that my subscription is expiring.
