I started using Net Nine Nine in February, and on their brochure, they specifically mentioned that it is a non-contract agreement, meaning I stay connected for as long as I pay the fee after 30 days. Two months later, on the 1st of May, I received a notification from my bank that my account had been billed by Net Nine Nine (after I just paid on the 20th of April). So I asked myself, where did they get the authority to take money from my account without my knowledge and when did our method of transaction change because for the past 2 months, I have been the one making the payments to stay connected, not them taking money from my account like it's a debit order. I am extremely disappointed by this company. They are no different from **** artists in my eyes now. I do not want anything to do with Net Nine Nine ever again.
