Appalling online service. Order 2 items that I have paid online by credit card and they didn't delivery saying that was out-of-stock. Then I order again with pay by cash on delivery and after 1 hour the keto bars arrived and they requested to pay by cash what I refused because I already paid and they told me that was out-of-stock what was not true. The delivery man didn't want leave my door knocking my door constantly then security was involved and in the end I was so fed up with all the situation that I decided to pay again by cash just not having noise at my door. So paying twice for the 2 items by card and by cash. I am disgusted by the service of carrefour.
