This may get long, so I apologise in advance and I'll try to include everything to save drip feeding.
My parents live backing onto a railway line and when it was originally put in they raised the land to keep the line level, so my parents house is set quite high. When they moved in they had a rubbish drive and decided about 18 months ago to get someone in to do something with it. It was bricked up around the edges levelled and tarmacked. Took the guy ages to do as he'd go away and leave it. Looked quite nice but then they started to get bit of an earthquake appearing around the highest edge and the wall at that point began bowing out.
Eventually he came back out and fobbed them off and eventually he put some concrete posts in from the pavement to support the wall. It hasn't improved things, it is still moving.
My parents have asked him several times to come and fix it with no joy. He's even told them that he's become a Christian and going to church 
like it excuses him or something.
They approached Trading Standards and were told to do whatever the process was which they did. He sent the letter back he was sent unopened and because of that TS won't handle the case because they said he obviously knows the system
They've even approached Dom and the team but Mum is finding it too upsetting to reply to them at the moment. She's just called me from the bank in floods of tears (which isn't like her at all) asking me to find some help from somewhere (here I am!) The bank are being really helpful and been on to her insurance company who can't help because she doesn't have the cover she would need. The bank need it sorting ASAP.
They don't know where to turn. They have four children living with them, two are disabled (one with CP and the other with HMS and ASD), and they're scared that the house will fall.
