Hailuo AI Subscription Trap After Trial Period

I signed up for a 3-day membership on a program called Hailuo AI and paid $3. However, after the 3 days ended, they charged me $49 from my account as a monthly subscription fee.

I want my money refunded. I did not intend to purchase a monthly plan, but they charged me for one anyway. There is no customer service available, and I am also unable to cancel my subscription.
