Support taking way too long to resolve queries

Uptil now I have had good service because I had no change. I then upgrade from a 10gig to a 40 gig LTE line. The upgrade was activated on Vox side on the 4th of March we are now on the 19th of March and the upgrade is still not done. I phoned twice. First time on Friday the 15th they told me it is on Telkom's side it should be up and running in an hour but could take 24 hours. It was on for a few minutes then went off again. I phoned again yesterday 18 March again was told it would take an hour and upto now the line is still not fixed. I have sent emails , whatsapps, messages on Facebook. Phoned a few times wasting airtime money because they take 10 minutes + to answer phones. Horrible horrible experience. I am expecting a Pro rata billing fix for March
