Oder was canceled but I didn't receive a refund

I ordered a TV 2 weeks ago but then my order was canceled because apparently it is out of stock. Now my worry is that you guys did not notify payflex so that means I must now pay for something I do not have. I have called the store couple of times but there was no resolution, I even called yesterday and the agent made me hold for more than 5 minutes and then she hung up and didn't even bother to call me back
