Poor service and lack of knowledge from staff

So what happen was I was ordering online from debonairs and so I used the Wicode to and I did not submit the order but they have deposited the money from account. Now when I call in to do an refund for the money that they took they tell me that they can't reverse the money and I'm lying that I made a purchase that didn't go through. The lady Tarryn from Merchant that I spoke to told me I should send proof that I ordered from debonairs and I called debonairs requesting for the proof and they told me that they don't have any order for me that was made. I then had to call RCS again only to still tell me that I'm must get proof. Like where the **** do they expect me to get the proof whereas no order was place when they took the money from my account. I'm really disappointed by RCS I don't know where they think I'm going to get the proof. One thing they should know I will not pay for something I did not get. I'm ****en ****ed off by the service I got from you guys, the whole time sending me to different departments like I'm some kind of ****en fool. If I don't receive the money back by today I swear I will not payback any amount that I owe to you guys.
