Be careful of J2 Efax. They offer a Free trial of their fax service. The trial does not work, your faxes are not sent they will pretend it's technical on YOUR side. (sorry, I have 20+ years in IT, they say this to the wrong guy ) EFAX.COM is just a SCAM! All they want is to get you to give them your credit card details. When you realize they service is garbage level quality, and ask them to terminate the supposed to be Free trial, they will not honor your cancellation request. Instead, they will charge your credit card for many months. They will even send bogus advertisement faxes to you. The only way to get your money out of these credit card frauders is to request a chargeback at your bank. If your bank don't want ask directly to VISA or MASTERCARD, because VISA policy on chargeback is not limited in time, you may ask a chargeback even one year later! When the scammers at EFAX.COM will get enough chargebacks their payment processor will refuse their business. You may also directly inform their payment processor that EFAX is a scam. Also, you should make aware the BBB in USA (www.bbb.org) of what happened to you, if they get many complains they likely forward the matters to relevant anti-fraud authorities.
