Inspection obligation for sellers?

I bought a notebook from Ebay at a retailer. The notebook was B-Ware. When the package arrived, a different notebook was included than I ordered and I told the seller and complained. The package sent back immediately, of course. It also arrived at the dealer and this paid me back my money. 14 days later I received a mail where the seller threatened me with court because I should have sent back a wrong notebook. Now I wonder what happened in these 14 days after receiving the package? Does not the seller have an immediate inspection obligation under the HGB?

I would ignore that.

You have received the wrong product and the seller has reversed the purchase according to the return. You can prove the process completely. Save all this for sure! (Screenshots as PDF)

What he is trying to do now has no contractual basis.

To ignore.

The obligation to reprimand exists only UNDER merchants.

In addition, it would not be applicable to a return anyway.

If you have replaced the notebook, you would have a very big problem.

I have the feeling the questioner could have exchanged the notebook…

You do not know for sure. If the TE has acted clean, that's the right course of action.

I DO BELIEVE in the church, I can't know it through a web-based platform.

Nice that you judge me for something I did not. Do you say anything in dubio pro reo? Apparently not. And then do not defame it? It can't be worse! You should feel ashamed!

I have neither defamed nor convicted you. I have commented on a possibility in the subjunctive.
