why no customer service helping , not even vitrual assistant?

about 9 days ago, I started a 7-day free trial of an Adobe plan ( monthly plan for firefly pro plus). Unfortunately, I forgot to cancel the trial before it ended. After the trial expired, Adobe tried to charge my account, but the payment did not go through because there were not enough funds.

I was unaware that a charge would be made automatically after the free trial ended. Right now, I’m unable to cancel the plan from my account settings because it says I need an active subscription , but I would like to avoid the payment being processed or the subscription being activated.

I also haven’t used any Adobe products or services since the free trial ended. Could you please help me cancel this plan and make sure no charges are made to my account? I understand there might be a cancellation fee for annual plans, but I would really like to avoid that if possible. I also understand there is a 14-day refund policy whivh is Adobe offers full refund if the subscription is cancelled within first 14 days(including trial), so if the payment has already gone through, I would appreciate your help in getting a refund.

Thank you very much for your help and understanding
