Would you kindly request a refund for my subscription to your account? I signed up today, in error (too expensive for me), and then canceled the subscription today -the same day. My bank account has a been charged $70.00! I hope you can help me. It is so difficult to deal with substack directly and the chatbot advised me to contact you directly through your account to authorize the refund. This was the only way I knew how to reach you. Many thanks.
