Dear , Razer Support

Hello, Razer support, please help me. I just topped up my Razer gold. And I need an OTP for my phone number, but the phone number I listed is one that I haven't used for a long time. Can I change it again? With a new number? Please help and cooperate. I have done the steps listed on Razer support but have not found a solution that allows me to change my old phone number to a new phone number.
