NeonBrite Fraud,never gor a refund, poor communication, product was inferior, false advertising. Dallas, Texas

I was looking into getting a dental retainer to replace one that was lost.  My biggest mistake was contacting this company.  First of all, the website is misleading.  There is a specific retainer I wanted with a particular function.  After reading the description on the website, I clicked the buy it button, expecting the product to do what it  said in the description.  I purchased both an upper and lower retainer from this company.  Here is what is on the website.

"When using this dental retainer, a metal wire shows, unlike the Essix retainer (which is clear or 'Invisible').  When one smiles others are able to see the dental retainer wire; retainers with the wire across the front teeth are used mostly to keep teeth from shifting, but can also be used to move teeth; That type is called a 'Hawley with Finger Springs'. Finger Springs are small clasps that add pressure to one side of the tooth, "moving" it along the retaining wire.

I assumed the retainer would help shift my teeth after reading the description. When I received the product, the upper did not fit properly.  The lower fit, but it did not move my teeth like I assumed from reading the description. 

Right around this time, I lost access to my email, and had to use a different email.  I explained this several times to the merchant, to clarify why my emails were being sent from a different address.  I told him my concerns and he promised a replacement.  Every time I would send this person an email, he would take weeks before ever replying.

 When he did reply, he would pretend that he did not know what I was talking about.  I explained the situation to him several times, and he promised replacements.  At one time, he told me he would be sending a new retainer in the mail with a tracking number.  This never happened.   What he did do was demand more money from me.

  After over a month of trying to get this matter resolved, I contacted my credit card company with a dispute.  The response I got from the merchant was that if I returned the product, I would get a refund.  I returned the product but never received a refund.  The merchant is a liar and a fraud.  He does not have clear policies about his services.  How can you tell a client that you will provide a refund and then after you receive the product, change our mind?  I have all of the emails that were sent to me as well as the form where he gives a written instruction for me to return the product.

In one of my emails, he rudely tells me to "Have a nice life."   This is after I told him that it was ridiculous for me to pay more money when he had already promised me free replacements at no extra cost.  Now I am stuck with this charge and no product to speak of.  The merchant does not wish to further communicate with me.  He pretends to not know what I am talking about eveytime I try to contact him.  After promising a refund, he then tells me that he cannot give me one.
