I've been toying around with ProtonMail premium service, so this isn't a direct reflection on ProtonVPN the product. However ProtonMail's support is abysmal. For me that hasn't been a direct reflection of the product, however getting anyone from ProtonMail to engage in a cognizant support conversation is next to impossible and takes days to get an answer. They don't seem to treat paying customers any different than those using free service by way of enhanced SLA on support tickets. My interactions have been so bad I've considered getting a refund on all my outstanding credit (hundreds of dollars for multiple users over multiple years).
I'm curious how this bleeds over into support of ProtonVPN.
