Bad service and no refund after paying and not receiving goods

Disgraceful service. I paid for a headset only to be informed 2 days after that they dont have stock, i asked for alternatives via email which was not sent until i complained days later. Naturally they suggested one set which was morew than double. They eventually after emails and calls said they would refund and i had to supply a confirmation of account. Nothin g has been done. Email after email and no refund. Do not trust them.
