They got the wrong meter(my neighbours actually) and even speaking to them for over 6 months, they've done nothing. All they need to do is send a guy to check and are still "investigating ", meanwhile they've instructed the debt collectors and even after agreeing to stop it till their investigations are done, those people keep on calling and bother you at work in hours. My sincere advice to anyone looking to use them, PLEASE DON'T. You'll be pulling your hair out and the customer service is so thick and useless, nothing would matter, neither a kettle test, photos and videos proving that they've got it wrong. But they'll again say that there is nothing on the file! Completely useless, believe me, save yourself from hassles and court notices. Use octopus & edf. They're way better.
