No goods and no refund

I placed an order over a month ago. It did not arrive. I enquired two weeks later as to its status and was told there had been a technical problem with their system. I asked for a refund in writing and telephonically and was promised this. I have received no such refund nor even an email to which I could respond with my banking details as I requested. Now I receive no correspondence except for blank emails and the phone goes unanswered.

Cybercellar is a **** that has ****** my money.
