Returned a jumper to purchase it in a smaller size. The reason I couldn't send it back as an exchange is because the size kept going out of stock. So I purchased a new one in smaller size and sent it back. When I placed this order I received £10 off for the whole order, but my refund has deducted the full £10 for one jumper. Jumper arrived as though it was used and returned. Contacted customer service to be told my issue couldn't be resolved.
