Useless MWEB

You cannot get hold of MWEB by telephone. You are placed on hold until you give up after an hour or so. I cannot find an e-mail address. On Whatsapp the bot directs you to a technician who wants you to do technical stuff which I DO NOT KNOW HOW TO DO. Requesting on the app for a technician to come out??? No answer on that request! then they close the session??????. No office to go to. To cancel my subscription....WHERE????
