Doesnt work

It used to work fine, but recently I tried to fax and it didnt send it. Still billed me $4.99 (requested and received a refund from Apple for that). And it keeps giving me a notification that I have an unsent fax, but its nowhere to be seen in the app. Then iFax asked me to write a review, so here it is.
