Bad service

I have logged a call on Monday 2nd Des for a faulty electric pre paid meter. I cant load pre paid electricity and is stuck on error 30. Today is 6 Des all ready. I could luckily make a plan, else i would be on day 5 without power. I phone every day, every day a different lie or like today, they leave me on the line for more than 20minutes until n gave up. Pathetic, if you have a issue you are in deep trouble with these people. I have ref number and everything, just nothing being done.
