Buy cheap Pay twice

I purchased a ONE-month subscription service from Depositohotos. There was no indication that this subscription would be renewed monthly, no email, no notification, nothing. When I saw that my credit card had been charged another $69.00 in April, I immediately contacted the company on their online customer chat and spoke with someone named "Sheena." She basically told me that I had bought a renewable subscription. Finally, she agreed to contact their Financial Department to see what they could do for me. She said that she would get back to me the following day. It is now May 2014, and I never heard from her. There may indeed be something in the very tiny fine print that says that the charge will be renewed monthly, but I have screenshots of the order form I filled out and the receipt I received from them, and nowhere is it mentioned that the charge will renew.
