Greedy company trying to get rid of early customers

In the early days I had good customer service from Home-Connect, but recently they have been completely unaccommodating. I am moving house and want to move my internet, which apparently means I have to cancel my plan and re-sign up. While this is annoying, it's not the end of the world.

But I have a great monthly rate for fibre as I've been a customer for nearly 3 years and now they will make me sign up at their current rate, which is R200 more than I'm currently paying. They are completely unwilling to grant me any incentive for my loyalty over the last 3 years. They clearly do not care
