Disappointed customer

Mr Price Home I am not happy with the service that I got at this store in Kempton Park festival Mall they did not allow me to return the 4 curtains that I bought and they even refused to put my money in a voucher card that I already have because I lost my receipt and they are short on my window so I lost a whole R2000 to them and curtains are still in its original packaging, I will never buy from them ever
