Are there any private email services
What exactly do you mean by private with regards to email? What is the problem you’re trying to solve.?
E-mail is not a private service by default. You can “try” to mitigate some privacy flaws using PGP for example but PGP is not widespread to be something useful.

Weird. Support was top tier when I had issues. I also own a business account for 30-35 people, and the issues we get are easily resolved by Tutanota. You most likely got a bad rep.
