Desk.com

Nothing beats a complaint management software like Desk.com for its feature wherein you can undo a message you have just sent to a client, whenever you feel like there's something wrong with what you just sent. With Desk.com, multiple users can all access the same information at a time from one location.

In Desk.com, you are not allowed to forward anything to anyone. Also, there is also a limitation on the number of values that you can enter as issue type and reseller. Other minor downsides include that there is no "check all" and "uncheck all" which can be very helpful in adding or removing content. Sadly, you have to do it one by one, and that is a problem for heavy numbers of content. Second, you can't insert images into emails or cases when you respond to clients.

With Desk.com, you give the clients the ability to set-up self-service supports. Additional to the great features they have, the multilingual support is another you can count on, too. You can also keep track on how long has it been since you have last replied to a complaint.
