what glitch item u buy...?

just curious do you guy experience something like this.

I made an order with 4 items but i only wanted to return 1 of it. And i request the return but it shows as to return 4 items.

Then i requested for picked up service but i only return only 1 of the items and once picked my money is refunded to my wallet for 4 items while i actually only want to refund 1 item only.

I thought they will check my return items before refund but now they refund straight after picked up. So ended up i getting the all the refund money and 3 items.

Not sure how will they handle this case later.
