Switch my coin order

Has anyone dealt with HH Rarities Coins or Joe Dell, I’ve placed 2 orders, 1 last year & one last week, and both times they screwed me – 1-888-793-3930. Even their email on their business card is bad – had to go on their website to get the correct email (www.hhcoins.com).They are located in Ronkonkoma, NYAnyway, my latest story is:I place an order for silver (money upfront – this is NOT uncommon) – 1957 through 1963 NGC Franklin Half Proof Dollars. All of these coins was to be proof 66. Mr. Dell talked me into buying a 1956 type 1 NGC Proof Franklin Half Dollar. The going price on the NGC site was $600 for a proof 67. He was going to charge me only $400 to make up for the last screw up. Instead, he sent me a PGCS PR 66. This coin, by the way, is only worth $210. I do NOT even collect PCGS coins – only NGC. In fact, he included a NGC storage box.Upon phoning him for the mistake, he claimed that they needed to make a profit and that I could not sent it back since he (Joe Dell) refused to give me a return number.DO YOU HAVE ANY SUGGESTIONS ON WHAT I CAN DO OR ANOTHER SITES THAT I CAN POST THE ABOVE INFORMATION?
