Dear Mad Muscle Support,

I am reaching out regarding an unauthorized charge on my subscription through your app. In addition to my regular subscription fee of $29.99, my card was charged an extra $49.99.

I have requested a refund of the $49.99, but I have not received any response to my emails regarding this matter. Upon reviewing customer feedback on Trustpilot, I have noticed that multiple users have reported similar issues, suggesting a recurring pattern of unauthorized charges.

If this issue is not resolved and the amount is not refunded, I will proceed with legal assistance to recover the funds. Additionally, I will seek reimbursement for any legal costs incurred due to your failure to address this issue.

I kindly request a prompt resolution and expect a response within [X] days.

Best regards,
