Decathlon UK Return Refund Delayed: Lost Discovery Gravel Bike Collection

I ordered a Gravel Bike Aluminium Frame Discovery Microshift Acolyte 1x8s (4930114) from Decathlon UK online on 30 May 2026 for £589.76. I realised I had chosen the wrong size, so I submitted a return request on 2 June and Decathlon arranged a collection for 12 June. I handed the bike over to Decathlon’s own collection team as instructed, but as of 14 July I have still not received my refund. The only explanation I have been given is that they “cannot find the bike”, even though it was collected by the courier arranged by Decathlon. I have contacted Decathlon customer service many times by email about this, but I either receive no reply or the issue is not resolved, and my refund is still missing. I find it unacceptable that a product collected through Decathlon’s own return process has been lost and that the customer is left without a refund. I request that Decathlon UK urgently investigates this missing return and issues my full refund of £589.76 without any further delay.
