Sharon, before you sent it back I hope you followed the return procedure on the website.
As long as you did, you will get your refund once they have recieved and processed the item. That usually takes about 1 week (based upon past experience with my own returns). Depending on your reason for returning it, they may deduct a restocking charge. Was something wrong with the item or did you just not like it?
Either way, sorry for your negative experience and I hope your return is processed soon.
