I've been a customer since 2011 (moved away a couple of years ago). Even though they didn't increase their nominal prices, my prices raised steadily during all that time. Usually with some minor amount of extra resources added without me requesting them.

Also, most of the time, reverting the increases would take renegotiating things with support. Recently, it changed into requiring destroying my machines and creating new ones from scratch, what besides an improvement, is still as hard as migrating to another provider.

Anyway, I was not entirely dissatisfied with them, but this one is a sleazy behavior.
