WeTransfer review: Wetransfer

Every month I receive a $50 unauthorizedcharge from WeTransfer on one of my credit cards. And every month I have to call the credit card company and tell them the unauthorized charge did not come from me.
Until I looked up, we transfer on the Internet. I did not even know what it was.
Today, I tried to find a phone number to call them, which when I called it, I disturbed a gentleman at his home residence. When I emailed Alex.Watson it came back as a MAILER DEMON.
It appears this company is working diligently to not be able to be contacted!
This makes me so angry as someone literally is stealing money and committing fraud in my name.
