I purchased a c# book order id (Nr-010503) december 2018 from madrasshoppe.com website. He confirmed my order and mail me due to our festival we are delay to send book in the appropriate time period please wait more days to send. I accepted their rule and festival so i was waiting for response and chat their customer support executive. He said our product is finished of stock. So we transfer amount against book.
I accepted no problem transfer my amount in my account. But today is 19 march 2019, in my order history details shows amount refunded and customer executive is not respond any mail and www.madrasshoppe.com is not having contact number. How can i contact directly to solve my problem. Guys, www.madrasshoppe.com is a fake website, which give you instant mail against you have order a book but not sending book and money.
