Managed VPS with 24/7 technical support (phone, chat, etc.)?

Hello,

I'm currently at FastComet, but I'm disappointed with the technical support options. They provide technical support only through their ticket system. So I'm looking for a new VPS provider that meets the following requirements:

Managed Linux VPS
24/7 technical support – telephone, live chat, ticket / contact form / email
Minimum quad-core CPU
At least 6 GB of RAM
At least 100 GB SSD
At least 5 TB bandwidth
cPanel / WHM / Softaculous
~ 90 USD
