I had a pre-loaded credit card of £50. I bought 1 main item: £40 and £10 worth of "filler items". I downloaded the app for 20% off - RESULT! USC emails me the next day to say my main item is unavailable and the remaining "filler items" are on their way. I dont want the filler items, i want the main item! So i try to find a telephone number - none available. So I message via the website and via the email address to immediately cancel my order - no response for 24 hours. I then find out that Sports Direct is the same company & I call them - the guy obviously deals with a lit of people and a DISGUSTING CUSTOMER (NON) SERVICE WALL comes up. He tells me that he will refund my products when they return to a warehouse (although I had never received any item) and I have to wait for a refund. I asked if the 20% will still be around - he said "No". There was not even a sorry - just a "Terms & Conditions state..." USC has really shattered the illusion of being a credible company & I will deliberately try to use other companies before I use USC or Sports Direct from now on.
