Have you taken all of this to the CEO yet? If not I strongly advise you to put a document bundle of all of this together and email it over. Tell them you’re being prejudiced against and that your case manager is making situations up to support their assertions and that you would be able to pay the AP if you weren’t up to your eyeballs in debt from your previous car. See what the CEO office says.
As for electricity debt i’m sorry you ended up like that we were spending £200 a month on diesel in 2020 so going from that to a ZS EV saved us a fortune but everyone uses cars differently so I can understand how you could end up spending more. Have you considered approaching the fund your energy provider has for those struggling? Octopus for example you fill in a few forms and create a budget and they then see what financial help they can offer too based on your budget. I’m sure others have the same, who are you with?
