Bad service

My internet went down on Sunday. When I called a call centre agent mentioned to someone she was near that she was speaking to an annoying customer in isiXhosa. I took her to take and she merely apologised. Her supervisor said that they would deal with the issue. Needless to say, it is now Tuesday and the fault has not been restored. I work from home and have lost 2 days work. No one seems to care! I'm definitely moving from them...its the third time in a year that they've messed me around.
