I think you shouldn't try to cancel on your own by saying it's too late because it will only lower your own rating.
I am displeased because I ship within 24 hours.
I received a request the day after my purchase to cancel my order because it had not been shipped, even though the estimated shipping time was 1 to 2 days.
I have never dealt with anyone like this before.
I do not want to purchase from this person again.
Please be careful if you deal with this person.
