Quick summary: commercial water company Castle Water supplies a small office we own (we use top floor, a tenant rents floor below). The invoices have been going to an old email address that I no longer have access to - I totally forgot they were going there and just failed to notice that bills hadn't been arriving. I must have ticked an 'email only invoice' box years ago and forgotten.
Anyway, the original bill was just over £100 but in the past few months they've added £700 in unpaid bill fees including almost £500 for a referral to a debt collection agency.
I only found out about this at work today when I got a call from said debt collection company who have said our water will get cut off if we don't pay the £800 bill tomorrow.
I know this is really sloppy of me but I am juggling a huge amount at the moment including recent loss of close family member and I just dropped the ball. We didn't get a single phone from Castle Water chasing up the bill - apparently they don't do that. We honestly weren't trying to dodge paying the bill and I could easily have paid it if I'd realised.
I've tried calling Castle Water to explain but they won't budge on it and are saying we can put in a complaint but we won't get anywhere and they will cut us off regardless unless we pay the full amount tomorrow.
I'm horribly stressed at the moment and this is making me feel physically ill.
Does anyone have any advice / know of anything we can do?
