Manager refuses to cancel and refund order

I placed an order by mistake online for the sunnyrock branch, because the online order system automatically defaulted to sunnyrock, I called the call center immediately and was told to call the branch were the order was placed to request a cancellation and refund , I called the branch and was informed by the lady on the phone that the manager does not allow refunds and cancellations. I wanted to move my order to the correct branch. I am now without the order or the money paid for it.
