Disappointment from the start

I pre-ordered a product online in November of 2014, and knew that the product launched world wide in the second week of December 2014. I had to wait until mid February 2015 before they finally had stock. Apparently they had problems at customs even though this is the sort of thing that they do every day. I eventually received an email stating that I need to pay the final amount before they can deliver the part to me. They gave me 3 payment options of which I chose option one, but they didn't give me any banking details. After a couple of days I phoned Orange to get the banking details and it took a week for them to send it to me. I finally got an email end of February 2015 with the banking details, the amount and the reference number that I should use. I paid the money as soon as possible. After waiting a couple of days with no confirmation I got an email stating that I need to pay an amount that is even more than the money I already paid. I phoned in and it apparently they sent me the wrong information, starting that I bought a smartphone as well even though I did not. So now it is almost 4 months after my pre-order and I have no product and was charged wrongfully.
