Paid for this app so I could send an urgent business related fax. Never sent! Kept saying failure that their server could not connect. I sent 2 emails to their support line but did not receive a reply. I believe they are a UK or German based company. Im truly bummed out and thought they would save the day, not make it worse. Buying this app looks like a gamble where there are so many other fax apps with perfect success rates. May have worked for many, NOT ME.
