mweb account impossible to cancel

I have had sim swap ***** thanks to Vodacom. Trying to change the phone number to get an OTP from mweb has proven very difficult and so I still have not managed to do so. So I decided to cancel my account. But.... For several weeks now I have been trying to cancel my mweb account. It seems completely impossible. mweb does not respond to queries on their app, to email or calls. I have been holding for 20 minutes and then was simply disconnected. A typical local company profiting from crime and being obnoxious by making it impossible to cancel their lousy service. Oh mighty mweb, please cancel my account!!!
