Prestige Sole online shop *******!

I purchased Nike Jordan’s off this online store on Instagram on 29 of September and they promise a 3-7 days delivery. It is the 27th of October and I have not received my sneakers, I have emailed, reached out to them via their Instagram messenger and they responded once. A person saying he’s Joshua saying my sneakers will be delivered on the 30th and then nothing. I have received no email correspondence of this delay. I need assistance with Prestige Soles online shop, to either send my sneakers or give me my money back.
