Wouldn’t use USC again. After five days waiting for the postage, received the wrong item. Unable to contact anyone (no helpline after 18:00) to see if a replacement could be sent out. (Wanted to resolve speedily so could take item on holiday) Still waiting to resolve 5 days later. Will have to get item posted back, get receipt from post office, keep the bag open to put postage receipt in, then seal bag and post!!!. Not known anything like it. In contrast, ordered from House of Fraser received the correct trainers two days later for the same price and I am ready for my holiday. USC has got something fundamentally wrong and if it continues I fear for its future.
