Don't buy from their online store. Don't! Worst customercare

I've had the worst experience with Guess online store. Basically it's looking like I've been ****med by Guess. I ordered 4 items and only received 3. I payed via payflex and was billed the full amount of R1200 up front. Guess did not inform me that they don't have the other item or if they're still going to send it. I sent them an email to which they didn't respond to. Also I ordered a black t-shirt but they sent me a white one without even enquiring if i would be interested in that option. I'm still yet to find out how to proceed because I feel like they ****med me. Why would such a big retail store not even respond to a customer's email. But the very next day after my complaint they send me their sale items. Used to have respect for their label, now not so much.
