Almost. The custmeer service today said, he will note down  that returning the item back to me was probably only a misunderstanding by the logistic guys and i should just return the same item back to them. I guess noone at the logistic center made a note regarding this.

At the first time i called of course and they just told me to return the wrong recieved item, what i did. I just wanted to know today, what the status of my return is.

So in the end they accepted your "wrong item" which wasn't sold by Amazon?

No, not yet. I have to return the item back to them and they will look into it.
Should I stick to this item, or get an other  similar looking and similar named item , and return it instead?

I would stick with whatever you sent, I think it's too late to go back now. Please keep us updated on your situation. Out of curiosity, what was the item you're trying to get?
