HBO Max/$5 auto payment discount

Does anyone know if I sign up for HBO Max do I lose my $5/month discount for auto payment? I don’t want HBO bad enough to lose my $5 discount. I have called support twice asking about this and they won’t tell me the answer, which is pretty infuriating. You hire people from different countries who don’t understand the question and you don’t train them well enough to answer the question and that’s the face you give your customer when they need help.
