Yes I could do a complex calculation to work out exactly how much they owe me (I've done that at least twice before for people moving out), I'm not sure they're going to pay all/any of it though, because they think that Pure Planet was very expensive compared to other providers, having spoken to other friends who live in our area (they don't understand the 6 month fixed direct debit process so don't understand why there is a closing payment to pay, do you have an idea of how I can best explain this to them? I've tried several times (over FB Messenger)) and think that Pure Planet are really difficult because the switch process isn't simple, they don't think, so they don't think that the house would've used Pure Planet for energy anyway if everyone had known all of the facts, and thus I'm blamed for taking the decision to switch to it in the first place, hence they might not pay me anything
I've lost at least £200 in this scenario.
I emailed the team in reply to the moving out email that they sent me, so if I just leave it as-is (I've 'Moved Out' in Pure Planet's eyes), they suggested that their energy won't be cut off, it's just that PP will bill them direct for the energy usage up to 1st August? That would suit me!
Thanks for all the help!!
