Boardwalk Buy Delivered product that does not work and refuses to respond to attempts to contact Internet

Purchased 2 S7 wireless chagers In Aug 2016. After sevral weeks of nothing, I responded to one of their numerous posts on facebook asking where the heck mine were. They demanded a photo of the confirmation email... like providing them their own confirmation order # was insufficient. Several weeks later I received the product. 

Not one, but BOTH of them did not work right out ot the box. Attempts to reach them have been ignored. I have told them to quit sending me email and they continue to harrass me. They send me an email that says I have to click a link on their email to get them to stop. 

I sent a reply stating that I am not going to click on any link that could compromise my computer or be used by someone who has already proven to me that they are dishonest to use my "click' to prove i agreed to whatever nonsense lies they wish to perpetrate. 

I am looking for agent of service information and considering my options. Thieves in my opinon. Nothing but liars and thieves.
