Baby's Den Took my order but I never received it. New York City Internet

 I purchased a diaper bag for my stroller on May 12, 2017. By the beginning of June I felt like I'd given ample time for the item to arrive (given the shipping was free). So I called the number on their website, nice lady tells me tracking had not updated since May 16 and that she should would look into and call me back. Well no one called or emailed back. I call them again June 15 and they act like they have no idea what's going on but lady offers to send a replacement order however now the original color I purchased is no longer available so I settle on another color. Tuesday June 20 rolls around so I call for updated tracking she says I should have got it but she will resend it. Email never comes so I call back a hour later and now this lady says it shipped out that day June 20 and was expedited to give the tracking 24 hours to update. Still no diaper bag, still no updated tracking and when I call they refuse to refund my money because they know it shipped but have no tracking to offer me. I'm done with them. Filing a paypal claim tonight.
