SuperJeweler.com Deceptive, Bait and Switch, Lies...over jewelry... Internet

I purchased a 1 carat wedding band set through SuperJeweler.com. The advertisment promised SI1-SI2 clarity for all diamonds. I was skeptical so I both called and emailed customer service and was reassured 100% that is what it would be and it would even come with a grading card stating so. I received a 1 carat wedding band set with a HUGE, clearly visible black carbon inclusion right on the face of the center stone. The side stones were severely included as well. I would have graded them all I3. The grading card graded it at SI3 which #1 isn't what I paid for, #2 isn't what I was promised over and over, and #3 wasn't what they advertised and sold me. SI3 isn't even a valid grade at reputable dealers. So I talked with customer service again who was so sorry that they sent me a ring that "I was not happy with." They would not accept that it was absolutely not the ring that they advertised and sold to me. I wanted this ring to work out so instead of taking the refund I wanted the exchange. Again I was told they would make it right and I was going to get a diamond hand picked BY THE COMPANY PRESIDENT to be SI1-SI2 as advertised!!!! Once through the return process they sent me a new ring. Guess what, the diamond hand picked to be SI1-SI2 from the company president still has eye visible inclusions! It was not a HUGE black carbon inclusion, but instead a HUGE white feather all the way across the crown. The accent diamonds were just as horrible as the first one. This one didn't even come with a grading card because they knew it wasn't SI1-SI2!! I took it to a jeweler for a second opinion and they graded it at I3. ARE YOU SERIOUS!!!?? I asked for them to send me an SI1-SI2 ring like the had promised, but Customer service said there was nothing that they could do and would only offer me a refund. Which would be great except I just wanted the ring I was sold. I asked for a discount that would reflect the quality of the ring I received, they said no. I asked for an apology for putting me through the whole situation, they said they had already been nice enough. This is a company that survives solely on the hope that their customers will not notice they didn't get what they paid for. Then waste so much of their time back and forth that they give up and just accept the poor quality rather than deal with them any further. The president of the company knowingly and willingly sent me a severely included diamond after knowing this whole situation. What does that tell you about the company. The kicker is they still have this piece up on their website advertised as SI1-SI2 even after I asked for them to change it to reflect the actual grade.
