We were transferred to Octopus after Shell were acquired by them. We were happy at first as we only knew them from their slick marketing. We were shocked to see our overall bills go up, their terrible and confusing presentation of the bills and MASSIVE "mistakes" - we were charged 6 thousand pounds for one month of electricity, completely obvious that it was an error when looking at the track record and their reading.. but was not rectified and had to be drawn to their attention through a Complaint. The new bill is completely confusing and still carries big errors, claiming we owe over 1 thousand still.... (funny how the "mistakes" are always in their favour!??). It is totally unacceptable that they can do this and leave it to waste customers time, without compensation to go through an correct THEIR mistakes! TERRRIBLE COMPANY - AVOID
