Poor service

Bad service. Been trying to fix my new application from Friday it’s Wednesday now and no help instead it’s a back and forth via email when I call them still I’m being told to wait for an sms I’m still waiting no electricity from Friday . When I call I get different consultants and I need to explain the same thing over and over again …. When you speak to them the consultants are so rude today I spoke to megan she was telling me how I only sent my application today at 1 when I told her to check all my emails from Friday then she didn’t say anything … I want to know how to deal with such situations ? This is unacceptable
