Signed up to Shell Energy and paid quarterly on variable rate- without even informing us we found ourselves with new suppliers Octopus Energy. Had no clue we were expected to pay monthly as never requested monthly pymts- although bills under my name they did not send bills to my email address so ended up twice paying on reminder message. Recently seen that they have registered late payment on my credit file - clearly not something that I have done intentionally as my credit rating is only 5 points from top score. I complained but they will not remove. On one occasion I rang to pay my bill and I was asked where the money was coming from- ermm-"the bank account I am paying you from!!??". Avoid switching to this energy supplier at all costs!!!
