Thank you for your message. Once an RMA reaches us the turn around time is pretty quick. We send a confirmation email to let you know we have received your item and then a further confirmation when the replacement order ships out.
If you have not received this then it is possible your item has not reached us yet.
I have sent you a private message to get some details from you, if you could reply to that I can look into this further for you.
