Nike...aturbury pathetic

I purchased a few pairs of sneakers not long ago when I got home I discovered that one of the pairs was 2 left so I call the store spoke to a person Thomas he didn't even make an effort because when I told him that I have 2 left foots he straight said that we out of stock ob that tekkie then I ask him to double check because I'm sure when we fitted there was a pair left and right he only then asked me for a model number and when I gave whats on the receipt of THEres he said that it not the style number after 20 mins of hessels I eventually got to speak to the superior as he said Named Sarah which I think was worst then the worker Thomas... No help what so ever only says we must get to the bottom of this like she was schooled to only say that. because when I asked her a simple question like can u check on the system if that style was bought from someone that same day so we can see if the right side is still in store she said that the system can't check that...I ask if Nike is so big store but don't even have a proper system that can check what was sold... c'mon I said all she said u wana fight and being a manager or supervisor.... DROPPED the call PERThatic for a store called NIKE
