I was a customer of First Utility which was fine & the problems occured when the company changed to Shell Energy. I had smart meters installed Feb 2019 & I moved out of the property Aug 2019, I paid by direct debit each month & when asked where I was living in Aug I provided my current address of the property I was then living at. In Oct 2019 I moved again & Nov 2019 £179 was taken out of my bank account by direct debit from them. As I am no longer a customer I can't access my online account. I got the bank to recall the direct debit. Dec 2019 I have been on the phone to them & they advised the gas smart meter wasn't ever working & the electricity meter was reset when it was installed. A common problem with the Seimans smart meters apparently. I said how would I know this? & how is this my problem? I also asked why it took them from Aug to Nov to produce that bill & how it is so high during the warmer months when they said it was the gas meter that was the problem. Back & fourth by email to then be told the electricity meter was also a problem & the bill is just shy of £300 but they will halve that as a gesture of goodwill. I said I'm not paying that & maintained that stance since 27th Dec 2019. I now need them to email me the deadlock letter & I am ready to send everything to the Ombudsman. I've never been a bad payer & they are treating me like this is my fault!
