Why should I report an Issue with Zef?

Pulling issues faced by users like you is a good way to draw attention of Zef to your problem using the strength of crowds. We have over 1,000,000 users and companies will listen to us.
We have developed a system that will try to get in touch with a company once an issue is reported and with lots of issues reported, companies will definitely listen.
Importantly, customers can learn from other customers in case the issue is a common problem that has been solved before.
If you are a Zef customer and are running into a problem, Justuseapp might not be the fastest and most effective way for you to solve the problem but at least you can warn others off using Zef.
