I have been a long time user and promoter of @Tutanota for my email as part of my effort to #degoogle. However, I'm unfortunately at an impasse where they overcharged my credit card a ridiculous amount and are not responding to me at all. Definitely a deal breaker.
Does someone have alternative privacy centred email providers to recommend? Preferably ones that have support in case there's a billing error. To save me the hassle of doing credit card charge backs.
