Did not agree to upgrade

To get support from Home-Connect is like in non-existent in the Accounts department. We received an email from Home-Connect regarding an upgrade and we sent an email back to say that we DO NOT want the upgrade. And guess what. They upgraded us even when we did not consent to the upgrade. We do not need the higher internet speed. Financially we just can't afford to be upgraded every year when everything goes up and our salaries stays the same. I always were for Home-Connect, but not anymore. I'm now at this point to cancel my subscription with Home-Connect and go to a much cheaper ISP were they will listen first to the customer and not just do what they think they can do, by putting up the prices by upgrading without the customer's consent
