Very bad customer service

So I ordered a **** eater from them online paid for it and received last week Thursday. I then tested it and it was not working. I notified them the very same day. I was told they would replace replace it. I was promised I would receive it yesterday and I never. They could not even let me know it was not coming. I have been calling and emailing and no one bothers to reply or answer the phone. This is not good client service at all.
