Never ever use this service provider

With most service providers after feeling our wifi was compromised we could log onto the backend on our pc and change passwords. So we decided to change our wifi password and logged into our account but to no avail.Instead our wifi connection was lost since Friday.This morning we told a technician will come on site to rectify the problem for a charge. Firstly what king of service provider doesnt allow consumer to change their own passwords.Where in the TandCs is it written you cannot change passwords by yourself.We have to call them to request a password change really.Already a nightmare with 3 days without wifi and still paying for a service which is not rendered!!!!and still want us to pay for a technician to come fix it. YALL MUST BE JOKING,YOU ARE ********!
