One star isn't even worthy .. ordered a bike in store for my sons birthday 20th April 17 the assistant processed the ordered n stated it would be delivered on the 19th perfect I thought ! When I returned home I realised that the bike was a medium not large so I cancelled that order and orders the large instead .. on the 19th we stayed in all day waiting for the delivery to our disappointment it never arrived !!it in fact came the Nxt day at lunchtime however too late as my son wanted it on the morning of his birthday.. we opened the box and the back gears were hanging off !! I called and spoke to Sonia who advises me to walk with the bike to the nearest bike shop to get it fixed as I had no transport and send them the receipt for a refund .i asked about my refund for the first bike to be told it was being processed ..she informed me I cudnt exchange until the original bike had been returned back to them .. so now I'm £320 out of pocket for two bikes my son still as no bike and when I called to spk to a manager I waited 3 days for them to return my call !! I called again and spoke to Beatrice who lnformee me that the manager miss OKSANA was unavailable to speak to me !!! Never will I shop In Decathlon again as their customer service is appalling !!!
