KFZ-Werkstatt Poellka not delivering what is ordered from them.

On 20/02/2023 I bought a "Mercedes Benz MB W211 W209 TV Tuner Module Control Unit *** Original" from the seller. When the unit was delivered to me, I got a totally different unit, that does not nearly resemble the photo that was on my invoice as well as the internet. Furthermore, the original manufacturers label was removed so that the unit could not be identified. I sent an e-mail to the seller, describing my issue and received an e-mail back requesting my address so that they can send me the right unit. I sent various emails after that to find out if the replacement unit has been sent and to get the tracking number. All these mails were just ignored. As I paid via an online paying platform. I lodged a dispute with the platform, after which the seller insisted that I must return the unit on my own cost, and once they receive it back they will refund my money. Now let us look at the mathematics: I paid 204.98 Euros for the product shipping included, as well as 26.33 Euros import duties. (Total 231,31 Euros) The cheapest quote I could get to send this unit back was 196,86 euros. So, the seller requires me to spend a total of 428.17 Euros (Purchasing price, shipping to South Africa, import duties as well as shipping back to Germany), and only receive back 204.98 Euros, resulting that I will have a loss of 223.19 Euros and that for the fact that the seller did not send me the item I ordered. Very convenient as the seller can re-sell this product again to someone else, whereas I have to suffer a huge loss. So be careful if ordering from this seller, both from the seller's website as well as his store on Ebay, as you might land yourself in the same situation.
