Mermaid Pools And Hot Tubs

Brought back vacuum as was not working and the cashier charged us 15% restocking fee, I suggested I exchange it and she said there would still be a 15% restocking fee Like really it does not work I just want to exchange it. She proceeded to tell me it was written on the bill. So i asked if I exchange it I still have to pay the 15% restocking fee and what if this one does not work as it was the display model left (the only one left) she said well if it does not work you have to pay 15% restocking again. So I just returned payed the 15% restocking fee but really I will never go there again
