Buyer has multiple bad reviews on Mercari. I like to give people the benefit of the doubt when the majority of their feedback is positive, but obviously this is difficult when most sellers give 5 stars regardless. Anyway, buyer demanded a return for an item because it wasn't the right size and didn't have a specific tag, even though the tags were shown in the listing photos and I provided the exact measurements. She said she didn't check the measurements because sometimes sellers don't measure correctly. This was also after she messaged me asking me to call USPS and take my hold off of her package... which I never put on hold. Her local post office messed up and she sent me this long message assuming that I held it because her payment didn't go through. She sells on Mercari as well so it's strange she doesn't know how it works after all this time. She has multiple other reviews by sellers saying she's exhausting to deal with and not worth selling to. I can't leave a review now that I've accepted the return (to avoid bad feedback) so this is my only way of warning other sellers.
