is there a better option than Intercom/Fin AI

from my experience Intercom isn't perfect (e.g. messages are not consistently showing up on the list, message from my app goes to my website live chat box)
it's an expensive software but all kinds of small problems.
Fin answers the questions but not really solving my problem
when asking for human agents, there were no reply for days

i'm sure that there are probably a few things that i didn't do right myself, but they just seem to not care about their users at all

is there a reliable one that you use for your startup? i need the AI chatbot plus the regular chatbox feature
