Identity theft / Fraud / Embezzlement Texas

On - -, 2015 I noticed an unauthorized and unrecognized charge on my American Express account which posted - -, 2015 in the amount of $2300.00 by a company named - - - -. On - -, 2015 I initiated a dispute with American Express related to this charge. I received correspondence from American Express on - -, 2015 stating that the merchant had submitted a market analysis report as evidence that the charge was valid along with a typed message on the back which contained a one-sided conversation by the merchant. Upon closer inspection of this merchant it appears the company is based in -, I live in the United States and have never done any business with anyone from -. The charges were reapplied to my account. I am attempting to further my dispute but do not know what supporting documentation I can provide showing that the charge was fraudulent other than the geographical limitations of an authorized transaction occurrence. I am continuing to dispute this matter.
