We have lived next door to this for 2 1/2 years now and it's heartbreaking.
We're at the point now we've been told to ring the police and on the emergency number, as well. But nothing happens - police get fobbed off by the and leave smiling and joking, every time. We've heard the 3 and 5 year olds next door called fuckers, cunts, bastard, idiot, little shit - you name it.
SS came out briefly, visited weekly then seemed to sign them off. NSPCC got things going and got the police involved, but now don't even bother to acknowledge emails. The police told us "the relevant agencies are involved".
These children remain alone in the house with two alcoholics (we assume they are alcoholics as years ago we lived next door to a registered alcoholic, and they buy booze buy the crate - even he didn't).
On Friday I heard the little girl crying and screaming, and the father shouting at the mother that "I've had five years of this shit now!" (the older child is five so I guess he meant parenthood). They are clearly two inadequates with all kinds of issues but nothing ever gets done and the children remain in their care.
Ring 999. Don't bother with the other police number - that is only logging incidents.
Email the NSPCC (but they will stop responding when this continues and bear in mind if people are abusing their kids, they're doing it repeatedly).
No-one gives a sod, any more, about children in these situations. I think the odd high profile case is collateral damage and the powers that be see it as cheaper to sack and pay off a high profile social worker, than it is to deal with the case.
I have become a cynic, and utterly lost all hope of these two kids being got to a place of safety. No-one cares, I suspect, because there'd be a lot of unemployed people if these scumbag 'parents' were actually dealt with.
(We saw them kicking the crap out of their dog in broad daylight and they got away with that too - because I didn't film it).
Record, btw. Get evidence.
My kids have got hardened to hearing it after over two years. I often feel like taking out a private court case if the police won't do them for child abuse - to sue them for abuse of my kids, having to live a few metres away from this. There needs to be some mechanism to deal with these situations - I hope you don't have years of this.
