Vumatel, shocking customer service

My Vuma connection went off on 19th June. I reported it on the 20th. It is now the 25th and it has not been resolved. All I get are emails saying the matter has been escalated. I have had no wifi fo 6 days. I have had to go on that whatsApp chat line almost everyday, getting a promise that it will be resolved. I waited the 72 hours [which is a ridiculous waiting time] after the fault was logged. But that has long gone.. And the fact that there is no number to do a voice call is insane. Having to type the same thing to different people everyday explaining my problem has been a nightmare. People actually work from home, you can't have no connection for a week. When you are paying for it. This is just shocking service from Vumatel
