Efax gave me one number based on their free service.  It would never work correctly.  They then, after the free trial was over, switched me over to the Efax Plus, but never gave me the new number.  They did, on the other hand, bill me for it.  When I brought this to their attention and asked for a refund, they refused, even though the customer service representative himself couldn't find the Efax Plus number.  The only way they could even trace that I had an account was via my credit card number.  Their final reason for refusing the refund was because I had received 3 faxes in my "inbox". ...
