Product: Credit card or prepaid card

USAA has been charging me false cash advance fees for purchasing on coinbase. When I started to purchase over a year ago they were not charging these fees. I actually used my USAA card because at the time they were supporting blockchain technology. I made calls to them and they blamed coinbase. I tried to contact coinbase and then after 6 months of back and forth I realized it was USAA charging me cash advance fees. I am purchasing into an application and utility token not crypto currency. Had USAA warned me or been honest in the beginning I would not of used their card. They kept telling me it was coinbase not them adding fees. I only used because they were crypto/blockchain supporters at the time. They were even building their own crypto currency. So now they added 1000 's of dollars in cash advance fees to my card over the last year. Every month Im being charged some crazy high interest fee for  cash advances. They then refunded and charged back again It's such a mess I don't understand what they did. Charges and chargebacks all over the place. Because they said it was coinbase I thought it was fixed but it wasn't at a all. I never would use a card for cash advance.I have been run around in circles for months and don't know what to do. My statements are in shambles because of them. Thanks in advance for all your help. 
Finally talked to USAA rep. Usaa admitted on phone they were not charging cash advance fees when I first started making app purchaces and they were crypto friendly. This is why I  chose them. I want to make sure XXXX  know I am absolutely not satisfied with the response. XXXX was actually rude and not at all understanding. I am actually mortified that this is even legal. Are there no usury laws? I will be starting a class action law suit and petition online next. Will research and see who is already suffering the same extortion from USAA and find the most effective media and social media outlets to be heard.
