I have called their 1-800 # they (Efax) told me "I am not their customer. They do not email non customers ever, therefore it must be spam on my end and I must contact my email provider to have the emails stopped. I contacted my email provider they told me the emails are coming from Efax. Efax has no opt out therefore I keep getting notifications that I do not want nor have signed up for.
Reason of review: Poor customer service.
