Parcel not received

I bought bedding from Home Choice in May 2020, the package was sent to an incorrect address and received by someone we don't know. I logged a query with Home Choice and sent all documents their ***** department needed. They have since been investigating, I have been doing follow ups and they keep saying that they are investigating, what's more painful is that I have paid for the parcel and someone else has it and Home Choice is doing absolutely nothing about it. This is unacceptable, you cannot **** people like this!?
