Disgusting customer service I waited 1 and a half hours on the live webchat only to be told to go into the store and ask I have an old refund card with 45 euro on it that was never used and doesnt have a pin on it and I wanted to ask if it was still valid even though I was told these cards never expire and after waiting so long they told me to go into the shop and ask and when I tried to call ikea they keep telling me that no one is available to answer my questions!
