We partnered with Tango to create a software for our company that would make our people's lives easier but instead of helping, the software created a lot of difficulties that resulted to double work and frustrations for our employees. Aside from the unreliable software that was full of bugs and system errors, we were disappointed with the lack other after-service support. It seemed like they don't want to deal with us anymore. It was a totally failed project with them, so beware!
