Please Help

I bought Two items which were a pair of Tommy Hilfiger underwear and a pair of Timberland boots on Dressinn on the 09/04/2020 and the items were delivered on the 06/10/2020. When I open the parcel I only find one pair of underwear and a pair of boot were missing. I send them emails from the day i find the parcel complaining about the incomplete order. They told me lock a complain in their block but, their block doesn't work and i was told that it is the only way i could be helped. I paid lots of money on the order and I'm afraid that I will loose my money. I don't have trust in them again and I wish someone could help me out there. The order number is ***1
