wasn't happy at USC own outlet within Sports Direct at Oxford St. Went there to collect on-line purchase made from USC & was told to go back upstairs to Sports Direct itself to collect it, what hassle. Got to the Sports Direct Till where the order was retrieved from the back and processed, and where on-line customers collecting items would then get a £5 voucher off their next purchase to use straight away or next time. Unfortunately the Sports Direct Cashier when asked about the Voucher said it could "only be used at Sports Direct", and not at USC. I explained the item was ordered from USC and not Sports Direct so why would i need it for Sports Direct. She Shrugged her shoulder. I then went back downstairs to USC to make further purchases and discovered the Voucher could indeed be use there. Lessons learn, lack of training on such an important yet basic knowledge which all assistants should know as i'm pretty sure other customers had been given this wrong information.
