What do you make of it?

Koppel takes 110cm with a closed coupling only 108cm. Exchange is not possible, return-costs have to bear itself and seller says on phone demand "you clarify with Amazon".
Some might see a fraudulent intention behind it to get a wrong item, return at his own expense and the seller can "sell" again.
Even worse, the packaging is clearly printed with a different company name and other address, so that one might suspect concealment. After all, the company indicated on the package, not sold on Amazon.
Please get the complete information of the seller and steer clear of it.
If so happens someone else, I am involved in the action to be taken.
