The VPS provided to this customer was a completely clean install of cPanel/CentOS (hardened by our VPS team) which we've set up for hundreds of other VPS clients without any performance issue - any performance issues were likely caused by the web application in use itself. Please note this was a fully managed solution - it is certainly possible to pay less for a faster server, but the level of service would not be nearly as high.

Voicemails are always responded to within 10 minutes if a call is not answered. This client's particular issues were not related to our services, but in fact because they had canceled their services with us before transferring their domain to their new service provider. Because of this they were experiencing downtime with their emails which was of course not our fault - but rather because their new provider was simply taking too long to set up their new account.

We were of course sympathetic and did offer alternative solutions to restore their email services in the meanwhile, but the client ultimately did not decide to take advantage of them.
