Decathlon offers extremely good value products at a very fair price. Fortunately I never had to contact their customer service but their in-store staff is very friendly and knowledgeable. The only point they could improve in my opinion is the delivery stage: they do not deliver for free and even with a fee, it takes longer to arrive than other online stores such as Wiggle.com for example. We reserved an item to be collected in store and it has been two weeks we are waiting for this item to be ready for collection, not even dispatched. I would and do recommend Decathlon around me.
