I am unable to change my plan. "We couldn't process your request. Please try again or contact support if the issue continues." the AI chatbot isnt working and i need to change my plan ASAP. HELP!!!

I have been trying to change my plan, but when im on the confirmation screen the website justs says “We couldn't process your request. Please try again or contact support if the issue continues.” the ai support is completely unresponsive. I have done everything i can think of. I am aiming to move to a premiere pro plan from my lightroom plan as offered by adobe, but it will not let me do this. I feel like im losing my mind. idek who im speaking to right now 😭. adobe can you fix this for me? This is a very annoying experience.
