Hornymatches.com / unauthorized deduction of money from my checking account
Someone used my checking account info and name to supposedly sign up for an account with hornymatches.com. I let people use my computer sometimes, but I never authorized anyone to use my information to sign up for any online dating service. When I noticed my bank statement showed a payment of $39.95 to Digi-Group, I immediately googled them to find out what they were. When I realized what it was they offer, I emailed them and requested my money back, explaining to them I never authorized them to take money from my account. They replied to my email stating that they track IP addresses and it was my computer that was used to set up the account. They also threatened to file fraud charges against me. What can I do to get my money back since they took it without my permission?
