Snt Sports poor service

Service absolutely pathetic. I ordered mma gloves and i needed it for a competition for the weekend so they delivered in time on Friday, however, they delivered the wrong item. I ordered red and white gloves because my fight gear is mainly red and they gave me blue. When i phoned in to enquire about their mistake the lady had a "no care attitude" and her response was, oh no its not the incorrect product its just blue, there's no more red available. I immediately requested a refund as i will not accept anything other than what i paid for. The lady told me that the courier will come collect the gloves from me Monday or Tuesday(16th/17th April). Since then ive phoned in every single day with her same response being "they will definitely be there tomorrow". It's now almost a week later, and I'm still sitting with these gloves and without my refund. This is horrible service and it will be the last i ever use SNT Sports as my supplier for my gear. Im very disappointed.
