Customer support incompetence

I tried to make a purchase through kinguin were as you are able to pay with skins. Done and dandy i thought. The skins were therafter sent to the middleman (skinsback) and I was awaiting my credits. Somewhere along the process the purchase was timed out with Kinguin were as the skins was already sent to Skinsback. I tried to contact Skinsback customer support to figure out if I was able to still get credits towards my Kinguin account. Their respons was to still let my skins go to them without confirming if I will get creditet and not. They insisted to still let them have my skins. I tried to reach out several times and didnt get a respons. Luckily the skins was still locked with 1 day to go so i was able to recover them with a 30day ban on steam. Do not trust Skinsback.
