I have had many occasions customer support has been extremely slow. I have had to wait a week to 2 weeks for replies or sometimes not get replies at all and have to chase it up.

Amazing product, terrible customer support. Tons of bugs. No one to help you work through them.
Pipefy even replied to my review here, but didn't actually reply to my support issue.

I thought it was a great product and used it for few years and its fine. However once we cancelled subscription, they kept charging. I was charged even after informing. The support as someone said here is indeed terrible. There is no resolution. My CC company has reversed charges, and Ive spoken to Pipefy contacts. Nothing helps and they keep charging. Hopefully either Ill resolve or have to cancel my card itself.
