Bank of America Credit Card Complaint

Bank of America Credit card department,

Illinois

i paid a company blue chip dev. - on -/-/2016.when i realized i had been taken i called my credit card to dispute this transaction.i was first told they could not find a billing error.it was not a billing error because i had given them my information.this was services not rendered to me. i am - years old, this is more of unfair and deceptive trade practice on the elderly.the bank went along with this fraud and found in their favor.this is only a portion of what they charged me.other cards responded favorably so how can some do and some dont. i dont feel as if the bank even looked into this.the amount charged has to be illegal.seems as if the bank just sent a form letter to bad.i dont know by law how much the bank or merchant are held responsible but this is thievery.i would expect more from my financial institution.
