This is the first time I have used decathlon for purchasing sports products. I will never use decathlon again, and I will continue to advise my many friends within the running and triathlon circle not to use decathlon. I returned an Item for exchange to have the same item sent back to me. I then had to use my own money to return the product t which cost me £5 I eventually decided to get a refund and take my business elsewhere. In the parcel I returned the receipt for my recorded delivery and proof of delivery. Only to be told paperwork is not kept and I will not be receiving a refund. I could not speak to any customer service representatives and could not make a formal complaint as all correspondence is by email. Shocking customer service all round! I received an email to advise that decathlon had called me, but no one had even left a voicemail to let me know this.
