In December of 2010 I had received an e-mail from the Sales Dept. requesting a new credit card number, as the one that they had on file for my billing had been cancelled due to a lost wallet. I returned an e-mail to E-Fax notifying them that I wished to terminate my account, as I had a new fax service. I did not receive a confirmation from them about the termination, and thought that the account had been terminated. Just today I realized in reviewing my credit card account that I have been continuing to be billed for their service monthly. I promptly called Customer Service and spent 1.5 hours on the phone between Level One Support in India, and Level Two Customer Support in the U.S. I did cancel my account, and my wife's through the Level One Support, however, they said that they could not provide any retroactive credits and had to transfer me to Level Two (approx. 45 min. wait on hold). When I finally was connected to Level Two, they were very rude and told me that my request would be sent to the Finance Dept. and they would respond in 3-5 business days, but that there was no one that I could talk with and I could not have any direct phone line for future communications. Basically I received the Brush Off.
Additionally, the e-Fax service requires proprietary softward (e-fax messenger) that cannot be easily viewed on mobile devices. There service is not superior in service or performance, but it IS MORE EXPENSIVE!
I would stay away from this Company as there are much better choices available in the marketplace.
