Has Anyone Else Found Zendesk Has Gone Downhill Big Time Lately

I have a problem where all of a sudden it won't accept an email for a ticket, my account is current, but I can only speak to a bot which is not even as good as doing a search.

Anyone got any other suggestions that are not too painful to migrate to?

I am using it for tracking issues across a globally spread team that are poorly integrated and I just use it as an issues tracker mostly, but with PM approval on change etc.

I wonder about Git, but have not used it like this before, does anyone have any input?
