MWEB, providing a great disservice!

I requested an "upgrade" to a 1 gigabit connection - the top-tier offering. I did this because working from home means I need a more-than-decent connection. I had a 200 mbit connection which, while unstable was at least working. I now get LESS than 200 mbits while I have to pay MORE! Even worse is the utter lack of proper communication with mweb. I have tried multiple times to get hold of a person and nothing. This is utterly despicable behaviour especially for someone who has been a VERY long term customer. They honestly don't give a damn about customer support.
