On Monday, XX/XX/XXXX, I purchased merchandise/consumer good " Bitcoin '' in the amount of {$470.00} from XXXX XXXX, a company based in XXXX, XXXX, with my Capital One MasterCard account. Then, on Tuesday, XX/XX/XXXX, I purchased merchandise/consumer good " Bitcoin '' in the amount of {$550.00} from XXXX XXXX, a company based in XXXX, XXXX, with the same Capital One MasterCard account. Bitcoin is a private, speculative non-cash " Cryptocurrency '' which I purchased for private investment purposes. It is no different than a purchase of any other merchandise item for investment purposes, i.e. : XXXX XXXX, XXXX XXXX, XXXX XXXX, etc., and it's value is only based on variable individual human perception. Despite it's description label of being a " currency '', it is NOT a traditional public currency as regulated, controlled, issued and recognized by established global Governments and their authorized, legal Banking institutions and Monetary Systems. ( Capital One itself does NOT even recognize or accept " Bitcoin '' as a legitimate legal currency! They will NOT accept " Bitcoin '' for payments, deposits, etc.! ) The dispute in question is not about the ( 2 ) above listed Capital One MasterCard charges - they are legitimate. It is regarding the fact that I have been charged " CASH ADVANCE INTEREST '' and a " CASH ADVANCE FEE '' for which I have received NO CASH! On XX/XX/XXXX, a FRAUDULENT CASH ADVANCE INTEREST CHARGE of {$2.00} was assessed, then on XX/XX/XXXX, a FRAUDULENT CASH ADVANCE FEE of {$16.00} was assessed, then on XX/XX/XXXX, another FRAUDULENT CASH ADVANCE INTEREST CHARGE of {$6.00} was assessed, and finally on XX/XX/XXXX, another FRAUDULENT CASH ADVANCE INTEREST CHARGE of {$2.00} was assessed. The grand total of these fraudulent charges comes to {$28.00}. When I contacted Capital One directly by telephone regarding these fraudulent fees/charges, they adamantly refused to do anything about these charges, AND STILL REFUSE TO - thus breaking the law. ( Interesting how a Big Bank can break U.S. Law at will, isn't it?! ) They also refused to give any legal proof that " Bitcoin '' is in fact " cash '', neither could they tell me where I received this " cash ''. CASH, as defined by XXXX XXXX XXXX   Dictionary, is : " Ready money ; whatever can be used as money without being converted into another form ; that which circulates as money, including bank-bills. XXXX v. XXXX, XXXX XXXX. XXXX ; XXXX XXXX XXXX, XXXX XXXX XXXX, XXXX XXXX. XXXX ; XXXX XXXX XXXX, XXXX XXXX ( XXXX ) XXXX ; XXXX XXXX XXXX, XXXX XXXX. ( XXXX. XXXX ) XXXX. '' As you can now CLEARLY see, " Bitcoin '' does NOT fit this legal definition whatsoever! These illegal actions by Capital One obviously constitute both FRAUD and THEFT, and DEMAND is hereby made that Capital One IMMEDIATELY withdraw these four FRAUDULENT and illegitimate " CASH ADVANCE '' related charges and credit back to my account the full amount of {$28.00} without any further delay WHATSOEVER! UNDER NO CIRCUMSTANCES WHATSOEVER will these Complaints cease until Capital One withdraws these four ( AND ANY FUTURE RELATED ) FRAUDULENT and illegitimate " CASH ADVANCE '' related charges and credit back to my account the full amount due!
