Hi, I moved out of a property in July 2018. I had been having troubles with the electricity and gas supplier Iresa who had never issued a single bill to me, they all read 0.00. They were very difficult to get in touch with, I opened support tickets which were closed down with no answer. The readings I provided also were not being input into their system (it was an online based account). Eventually I got through on the phone and spoke to a boy named Hillary and explain that I couldn't pay until they produced an actual bill and I was moving soon. He promised this would be sorted in the next few days and he would make sure I received the bill. He said something strange like 'i don't know how much longer I'll even be here', which was a bit crypic. Shortly after that they went into administration. I didn't get the bill from Iresa as promised, after I moved I had my post fowarded onto me and nothing came there and my online account still read nil until the website was closed down. None of these utility companies every seem to send letters. After I moved I also changed my email. I used to check my old one occasionally and realised I had started receiving communications to my email from Octopus who I guess had taken over Iresa customers which was in August 2018. As I understand it, it was compulsory for customers to be switched to octopus from iresa as they had gone bust, and you had to switch to octopus, who were more expensive, whether you liked it or not. The account was later switched to a new supplier in March 2019 and I received a 'sorry you're leaving email', which I presume was the new occupier switching the account. I realise now that I should have at least got in touch to explain I didn't live there but at the time I was suffering a bereavement and nothing in the world else seemed to matter, and silly things like utilities at an old property were the very last thing on my mind. My whole world was falling apart and I didn't want to have to deal with some utility company I'd had nothing to do with. I also assumed that the occupier at the other end would be dealing with their own utilities and inform them of their move. I realise now that when Octopus switched over from Iresa they just took my name and slapped it on the account without checking who the tenant was. I had told Iresa about my move but it evidently had not been communnicated to Octopus. They started emailing me large bills for around £800 to my email, which included an apparent arrears of around £300 from Iresa. I never received any letters in the post from either company, eventhough all of my mail was fowarded onto. Now at my new address I have received a letter from someone called UKSearchLimited with my name and indicating a utility debt of around £800 on behalf of their client octopus. And that if I don't respond within 7 days they will escalate the matter to recover the debit. I do not know how they got my address as my credit statement is clear and doesn't show any searches. I understand that since Iresa did not produce a bill within a year, some or all of that may be unenforecable. However, I don't want to pay all that money to Octopus for a service they have never provided me, and I never signed up to. Since I did not yet contact Ocotopus I am wondering if I should first contact them to explain the situation?
