MWeb don't need mine or anyone else's money

I have spent weeks trying to get hold of the sales team to upgrade. I spent the entire day today (8th Jan 2025) trying to get through on their live chat. No one answers. The accounts and billing agents answer and then put you through to sales.... still no answer. Shockingly bad. Now I want to cancel instead of upgrading. But how do I do that, no one answers.... :-(
