Bad service and client care

I ordered an item on 21/02/2023. Received the wrong item, and now 2 weeks later after numerous mails, I still don't get any response. Out of the blue a company wants to collect the wrong item, never happened. I call LM, only when they have collected and received the wrong item will they process the original one again. They got the correct amount from me and immediately, so I said they can refund me and collect the wrong item whenever they wanted to since it wasn't mine and I received nothing for my money paid. They must also first collect and receive before they refund. Nowhere in there is a feeling for the client, will NEVER buy from them again....NEVER
