Rip my wifi

Honestly so disappointed with the service. My wifi hasn't been working for 4 days and after calling 4 times and messaging constantly, trying desperately to get hold of someone, they eventually come and confirm the router is stuffed. The technician set up everything and then copied the password down wrong. After loadshedding the router came back up and the name was different??! Now I can't even get into the ip address. And talking over WhatsApp? Id have a better chance of solving south Africa's power problems than getting a decent response.
