The customer service is the worst I have ever came across. If you buy here you should pray to the God that something doesn't go wrong because the customer service won't even escalate your issue to a supervisor. They randomly changed the shoe sizes and they expect you to pay for return shipping and the exchange one when it's their fault for not providing you with the size chart online. The one they send you is 2cm off the one one you can google yourself. The customer care agent will show you no empathy, will never say they are sorry, AND for some reason... according to Killstar the Ireland is not in the UK so the "free shipping" policy does not include it. Also, any effort to have your interaction escalated to anyone higher than mere agent will be completely ignored and replaced with generic responses. A mere €10 credit would suffice for the issue, or would should that someone cares for something other than your money. Now I'm stuck with €45 worth of shipping charges or with decision to keep the over-sized shoes. The products are good, but the way this company and their customer support treats you as their customer is pure garbage.
