MWEB the worst ISP

I've been attempting to cancel my subscription since yesterday. I phoned 5 times yesterday waiting to speak to an agent. My call was answered once but the agent were not able to assist me and had to transfer me. Including this one answered call after being transferred the call is dropped after waiting for 20 minutes. I've left an comment on their Facebook page to which they asked my contact details for them to contact me, it's nearly 24 hours later still no contact.

On there website they have an option to converse with a bot, but when you click on the link it says service currently not available. There is also an option on the Facebook page to message them, but you get a message that the service is not available currently.

Can it get any worse?
