I bought my first makeup purchase off of an Instagram seller about a month ago and she shipped it within two days. I was given a tracking code that worked for about 4 days and then never updated again. It's been stuck at the same location since. I paid a pretty penny for my LE lipsticks and they haven't arrived. I saved up to buy those and feel ripped off. I messaged her about this and she kept asking me to wait and that she wasn't getting any help from USPS etc. She said she's willing to refund me half of what I paid not including shipping. Is that normal? That's a lot of money I'm losing out on but I don't know how this works. Any advice?
