VOLISA Jewelry Etsy.com Does Not Honor Refund Policy Los Angeles, CA Internet

I placed an order on the website for a mens ring and received it on 8/28/14.  The ring I bought for $1,450 did not look like the picture on their website.  Quality was poor.  I contacted seller on 9/2/14 to return the ring. There was no phone number to call, only an email.  The website states that there is a 30 DAY MONEY BACK GUARANTEE.  It was only 4 DAYS and the seller refused to take the ring back and accused me of blackmailing them because I told them I was going to contact my credit card company to dispute the charge.  The website also states 100% MONEY BACK GUARANTEED.  I would recommend that no one ever purschase from this seller.  They are obviously dishonest because they advertise a specific refund policy but they do not actually honor it.  I have screen shots from their website documenting everything as well as the emials from the seller refusing to refund my purchase and accusing me of blackmail because I was going to contact my credit card company.  This is a perfect example of why credit card companies allow you to dispute a charge.  Go to another jeweler.
