Spaces Design Quarter, downgrading customer service while upgrading offices

We have been loyal customers for the last 8-9 years. Since the change from The Business Centre to Spaces it seems that they lost the plot. Service is shocking, their portal does not work and their boardroom rentals have tripled in price. I have been trying to terminate my agreement for the last week, Was told to do it on the portal by the center manager who clearly does not really want to assist or get involved to sort this out. How can you not terminate via email?? Their system does not allow me to cancel the agreement online and the helpdesk email keeps bouncing back? I eventually had to call the help desk and a very unfriendly lady tried to assist me like she is doing me a favor! I am fuming. How on earth can you treat loyal customers like this?? I expected things to get better not worse. Looking for new office space.
