ARC online - uncontactable and no tracking for orders

I placed an order online on Arc for two beauty products on 16th December. I got a order confirmation on email but the order had no tracking. I didn't worry about too much until today when it occurred to me that it has been two days and I have had no updates on shipping my order. I contacted the call centre and sat waiting to speak to a consultant for 30mins without an answer and was forced to hang up. I emailed a query to the suggested email address and received an email response that someone would come back to me. Nobody has come back to me. I then decided to go in to the closest store, they informed me that the online Arc is run completely separately from the retail store. They apologised and acknowledged that they had had similar issues with customers coming in and needing assistance. So I am now sitting without my order, no ability to contact the company for help as you cant get through, no ability to check the status of the order and tracking. BEWARE!!!! DO NOT ORDER ONLINE WITH ARC!!!
