Misinformation and blatant lies

I have app**** for an upgrade on my internet connection which the agent told me would take place instantaneously. Later on I not only find out that it was a lie but it would take 72 hours which was supposed to be working by Friday 20th of March 2015. It is Monday 23rd and not only it hasn't been upgraded, but I haven't been notified about the progress at all. I spoke to Chris (call centre manager) on Wednesday 18th and he said he'd put me on a high priority list and that obviously hasn't happened. I now spent over 1 hour on the phone and all they can say is that there is nothing they can do for me. Really? There's NOTHING they can do? The people that are supposed to help can do NOTHING? That is a completely unacceptable response! How can a company as big as Telkom not be able to assist me? This is absolutely disrespectful!
