Smartfax Can't cancel free trial Internet

What a ripoff internet fax comany!!! They give a free trial which is impossible to cancel with the instructions they give. After entering info into smartfax.com/cancel it says to hit the chat button below to complete cancellation. Unfortunately, there is no chat button. I emailed customer service saying that I want to cancel my free trial but they only got back to me after they charged my card. They wrote to follow the instructions on the website or call a toll free number to cancel. I then emailed them and said the website gives wrong instructions and there is no chat button!!! They responded by saying they can not cancel via email. I called them today and they finally cancelled the service. I said that I want a refund so they transferred to a "supervisor" who never picked up the phone. Was on hold for 30min. Called back and the same thing happened again. Then they sent me an email that they will charge me prorated for this month. Bunch of Indian scammers! Never deal with this company! I will be sending those dirtbags the link to this warning.
