Mochi — Didn't get the refund

I returned an order on mochi website one month ago but didn't get the refund till now. Such a bad customer service they provide. None of their customer care contact number works. It's been more than a month since I'm waiting for the refund but I didn't get it. Such a bad website. I've never had this bad experience with any of the online websites. I won't recomend anyone to buy from mochi brand.
