Mweb disconnected

2 weeks ago my wifi password was changed, no notification was given just changed. The password originally given to me and the one on the Mweb App is the same. After holding on the line for 40 minutes for an agent I'm told I'm using the incorrect key. Today my wifi is cut. Debit went off my card on the 20th, I received a notification to say payment wasn't received I then paid again, I call the help desk again a 40+ minute wait only to be told I need to pay again and have the phone disconnected without any further assistance. So I'm going to be paying R529 X3 for my service this month. Not to mention that my account is in a credit state. I now have no wifi and unable to work.
