Bill Matrix review: Unauthorized debit card charges

I just noticed a huge charged placed on my debit card for $742 and change by a company named BillMatrix. I've never heard about this company or have done business with them in my life. Upon further investigating, this company has been taking payments of $33 and changes several times since June 30th! Sometimes even twice a month! Either someone hacked my debit card or this BillMatrix is a scam company and when I called their customer service they couldn't help me without an account #. So you're able to take payments from a debit card clearly not the same of that "user" but can't help me locate the person(s) responsible for these unauthorized charges? Cool! Hope my bank comes and get your fraudulent [censored]!
