I've requested for a exchange of my heels which were short for me so i applied for a bigger size.. My product was picked up successfully and i got the message also but it's been a week now and i didn't get anything in exchange yet and there is no update and when I try to contact the customer care service of street style store they don't response so please help me get my product I've already paid for it
