Nike buyer

Ordered some pairs of Nike running socks (54 EUR), May, 26th. Until now, 3 weeks later, nothing received, no money payback, nothing. I've sent an email to their customer support, June 3th, one email back "have forwarded your case to our department, so they will try to locate your order", since then quiet. I've sent several reminders, no reaction. Company to avoid, waste-of-time and money.
