CBI*MalwareBytes review: unauthorized credit card charges

There was an amount charged to my Bank America card on 12/27/2018 for $43.19. Reference #4546... I did not authorize this payment nor download their product. I removed it over a year ago when I went with another, better, company. They were contacted at the time of removal, so this charge is fraudulent. I want to get my money back and to report them for this transaction.
