I bought 4 tires on steel rims in September 2018 through the eBay shop of mein-reifen-outlet.de. They were also delivered relatively quickly, with one tire being delivered incorrectly. So wrong delivery complained. A fourth correct tire was delivered relatively quickly. I am still waiting for a return label for the faulty tire despite multiple customer service requirements. There is no response at all to e-mails and, on the phone, after a long queue - provided you don't fly out in between - handled dubiously. At the same time, my eBay purchase was canceled and the total amount repaid. Does not make sense? Right, I saw it that way and had therefore contacted Delticom's customer service several times. Reaction? Complete failure! So you can of course also ensure that you do not get any negative comments. Apparently they didn't want tires or money from me. Now, in May 2020 (!), There is a warning from Delticom that my credit card could not be charged (I had previously paid with PayPal! Which credit card do you want to charge?) And I have to pay the total amount + reminder fee within 4 days , otherwise a debt collection company would be commissioned and a Schufa entry would be made. Sorry, what can I do if your customer service is unable to respond to my emails? Your dealings with customers are an absolute cheek! In the future, I will avoid the entire Delticom group and have actively been buying something there! Highly dubious and definitely a black sheep among the dealers!
