Lucky Brand Women's Sweater, Size Large, NWT

I don't need this cardigan because I already have one. (A Christmas gift from my daughter.) This is brand new. It was an accidental purchase that I made in the middle of the night AFTER I FELL ASLEEP. I did not know that I purchased it until 3 days later when I was notified that "my purchase has shipped!" Huh?? I was not allowed to return this by Poshmark support! (See 2nd photo.) I am asking the same price that I paid for it. Please help me recoup the money that I was going to use for Christmas presents for my children, their spouses, and my 5 grandchildren? I am a disabled senior citizen who relies on the income from Poshmark to make extra money. Poshmark simply doesn't care about it and neither does the seller 😮‍💨
