I can’t refund a item and i have already refunded the same thing so please let me refund it

Apple has given you their answer.

It kind of seems like you are abusing the refund policy if you keep buying the same thing, then asking for a refund.

No.

This is a user to user support forum.

Apple is not here.

Seems you have already requested a refund and been denied.

Nothing we can do for you.

Seems it is not eligible for a refund. Which, makes sense as purchases are considered final.
