Order mot received and failure to communicate

I ordered a pair of sneakers from this company on the 26th of July 2024. I still have not yet received my sneaker. They offered a replacement before the 1st of August and with that offer, I had to go pillar to post trying to respond with my replacement. On the 5th of August they finally processed the order and I received delivery details thereafter. The order was supposed to be delivered on Thursday last week. This was not done. Upon calling the delivery company, I was told that the parcels were lost and that Madison should have brought this to my attention. But that wasn't done. I would like my sneaker by this week!!!
