I bought 2 batches of Uniqlo x Marimekko clothes and made 2 returns via Collect plus each on the same day on which I had received the delivery. After 3 weeks I hadn’t heard anything on either return so I wrote to Customer Service. The next day I got an automated email talking about ‘my order’ and saying it will take up to 14 days to process my refund. Added to the 21 days, that’s over 5 weeks before I get my refund on the first order. Haven’t heard anything in the second return. Meanwhile I have to remember all of this. The returns service is abysmal. My daughter uses ASOS regularly and it’s so slick compared to the Uniqlo process. The collaboration with Marmimekko is great though.
