TERRIBLE! Their communication process is ridiculously overcomplicated to make you loose track and miss payments. They won't just email the bill like every other company. Instead they send you a link, which takes you to their website, where you have to log in, then find the account section, then go through a list of documents, none of which are labeled with the bill date or amount, but instead you must download the pdf document just to receive your monthly bill! Then if you miss one they add insane late charges for hundred of pounds without warning or providing sufficient breakdown of how they are even calculated. Then they threaten you with disconnection which comes with an additional £420 fee on top for the disconnection. We finally just left them after hours on the phone fighting the disconnection charge and I'm so happy to never deal with these sheisters ever again!
