Seller Hasn't Shipped

Ordered a toy lot on 8/2. The seller created the label next day, but the tracking never scanned in after a couple days, so I inquired. She claimed she needed to get a bigger box. Ok, no biggie. After a few days she sent a pic of the label, unattached to the box but on top of a box. Said she had it scheduled for porch pickup. Then that didn't happen either. I asked yesterday 8/11, she said they had storms and the postman marked it as picked up but it wasn't. Said she'd run it to the post office. At this point I already contacted marketplace to say the item hadn't been delivered. This morning I get a message asking me to accept the package. The same one that she hadn't sent as of yesterday afternoon and said so in the chat. The same one that the tracking has never been scanned. I'm at the end of my rope. I gotta wait another day before I can make a claim though because I had already contacted marketplace that the item wasn't delivered. Shouldn't it know the tracking wasn't ever scanned in?! I'm probably not going to use marketplace after this.
