Poor Customer Service - Not interested in looking after clients

I was the unwitting casualty of my original and brilliant hosting solution provider, JCW Hosting, being bought out by an entity which has changed names a few time and is currently 1-Grid.

As a consequence of this, my service costs have all gone up substantially, without me being consulted about these increases. Further, my billing mechanism and rules related to the service offering I purchased have been unilaterally changed by 1-Grid and I am now in a position, where without consultation with me, without requesting my buy-in or agreement in any way, shape or form, I have gone from being able to manually choose to renew or maintain my annual services, to one in which 1-Grid unilaterally decided to auto-renew services "on my behalf" then bundle these together on one invoice, so that I cannot pay for the service I want without having to pay for the services I may not want that are on the same invoice, and when I want to cancel, I get told that I have to request cancellation, which will take 3 days, and for which cancellation I will have to pay a fee for services I did not request to be renewed in the first place.

To add insult to injury, when I asked to speak to a manager, I was advised that nobody in management takes calls from clients. The absence of any care about my situation by the consultant who took my call was just the icing on the cake.
