Dear OpenAI Customer Support,
I am writing to express my frustration and disappointment regarding the recent rejection of my credit card when attempting to make a GPT Plus purchase on your website.
I would appreciate it if you could provide me with a clear explanation for the rejection of my payment and advise on any steps I can take to resolve this issue.
I am eager to continue using OpenAI’s services and products, but this experience has left a sour taste in my mouth. I hope that we can resolve this matter promptly, and I look forward to hearing back from you soon.
Thank you for your attention
