tanzanite international diamonds international and carnival cruise lines DI/TI has misrepresented their product and refuse to refund my money 1 hour after purchase georgetown, Internet

i recently took a cruise with carnival cruise lines on cruise ship Valor.december 18th-december 24th.hile on my cruise i attended a tanzanite and diamond seminar where carnival cruise lines promotes diamonds international aka tanzanite international and reassured all cruisers that if they had any problems that carnival cruise lines will stand behind them..so earning so much trust by some of us cruisers we arrived in georgetown,grand cayman on december 21st 2011.. i purchased what was represented to me as a 1 carat cushion cut tanzanite with .30 carats in diamonds set in white gold for 699.00.

when i left the store i went with my friends to a local restaurant around the corner for lunch..during my lunch i pulled the ring out to show my friends.thats when my friend brought to my attention when she saw on the appraisal from TI/DI that the carat and gold had a line drawn through it and sterling silver had been written in.i have never bought sterling silver for my private collection nor would i ever have paid 699.00 for any piece of sterling silver.

i immediately took the ring back to TI and the woman refused to refund my money and she stated to me"you knew what you were purchasing"and pushed the item back to me and said you will have to take it up with headquarters in new york.knowing i had to get to my ship in30 min she was aware i couldnt stand and argue with her. 

upon my return to the U.S. i contacted TI/DI in new york and they have refused to refund my money and the best they could offer was a store credit.i explained to them i did not want a store credit. if they were misrepresenting their products why would i want anything else from them??i bought a ring that i was told it was white gold and only an hour later discovered that the sales associate that filled out the appraisal had written in sterling silver and scratched through carats & gold and a store that wouldnt refund your money an hour after purchase for what was misrepresented by one sales associate was a store i would never do business with again.

i wrote TI/DI a 2 page letter and enclosed it with the ring that i had purchased and when i asked TI for their address in new york the woman states "if you do not have an authorization claim number for a rturn your package will be returned to you.

i insured the package for 700.00 and sent certified mail to the address 38 west 48th street new york new york.i informed master card that i want this charge removed and that the item was returned via mail.. i have not received a credit back on my master card nor have i heard anything from TI/DI
