Question
I want to cancel the first plan and get a refund of 37000 won that was charged twice.
I paid the Premier monthly subscription fee on December 28, 2020.
After that, I paid for the new plan on January 26th this year.
However, 37,000 won was spent as the plan that I applied for on December 28 was not canceled. Therefore, I want to cancel the first plan and get a refund of 37000 won that was charged twice.
