Customer service is none existent. If you can get through on the phone which is very difficult they are only interested in their own opinion. Website will only direct you to stock answers. Tried e-mailing but responses were obviously from an automatic system that picked out key words and provided stock answers rather than answering the question. A lot of problems with arranging installation of smart meter. Increased monthly direct debit from £36 to £209 despite the fact that I was already £136 in credit. Will be changing to another supplier as soon as my contract is up.
