Same as below Ofgem website says…
Same as below Ofgem website says Northumbria ceased trading in July. My bank referred me to British Gas who said they supplied me during the time Northumbria billed me and took over directly from Zebra who ceased trading 3 November 2021. Switch didn't give DD details to British Gas so I now have £2K of bills built up with them. BG are asking me to set up a DD but I am honestly not that up for it given this experience. BG said Northumbria and Ofgem are 'working on it' and that I can't make a complaint to them. My bank is being difficult about covering this under direct debit guarantee as they say they need proof I have tried and failed to contact Northumbria etc etc first. They also say they wont report as fraud as I 'know' the supplier. Finally got hold of ofgem who say I should report the transaction as fraud as they definitely haven't been my supplier
