Bad and poor customer service ever

Horrible customer service treating customers like **** they even laugh at you when you complain because there's no reparcations no accountability this store needs to train their store managers and regional managers I bought the sneakers elles lime green for my fiancee since last month on the 27th they say they didn't have in in store they will collect at Jubilee mall waited for 3 weeks I went crazy on them when they brought is back it's a wrong size now they want us to wait another 7 to 24 working days for another sneakers jam no longer interested I want a refund now they don't want to refund us
