Business ProfileforDesign A Stone

I purchased online a stone from this company that was to be monogram. This was to be a birthday gift for my daughter. It was delivered to my daughter, but as you can see in the enclosed photo, it was chipped. I paid. $105.93 This amount is with the 40% discount coupon that they offer me that day. The company, a ********, replied via email saying they would replace the stone. I asked if I was to return it at their expense. I received no reply with returning the stone that was broke, moving forward. My daughter received the replacement stone, but I received my charge card, bill much to my dismay, it showed the $105.93 charge that I paid and they gave me credit for that amount. But I was charged now. $171.20!! so I communicated back with ******** and she said I was contacting the wrong company, then she said there is no order for this then she said they can’t find any information. But then again, she replied via email and said they cannot give me the coupon discount for the second order. It was not a second order it was replacement for a damage product that we received. I should have only been charged once for the amount that I paid. Her reply is we’re not giving a coupon on the second one I would’ve never purchased this product at the original price that they are now charging me. I would never have done that. What Drew my attention to purchasing this product was the coupon discount I want the amount of $171.20 to be given credit on my card and only pay for $105.93. Please if there is anything that you can do to help assist with this, it would be most appreciated. There is no way other than email to get in contact with this business. There was a phone number when I looked up the company but no one answers it, and the line is not even Stating that it is for design A Stone. It states the product is made in the USA, but they leave an email address to get in touch with someone. It is very difficult.
