4 tires were advertised online and ordered by me (Sottozero 3). After my order were still 4 tires in stock. A call to the customer service, who could hardly speak German, brought no clarity. On the simple question: "Are the tires I bought in stock at all, because the same amount is still offered by you?" I constantly received only the answer "I can not say that, I do not see that If quantity under 8 then probably not ...." And then I should transfer this statement just under 2000 euros ... without words.
