First: There's no chance they have a real lawyer. If they did, they'd redirect every single person to them.
The problem with the route of court-action is that once AT don't show up to court, and the customer is favoured in the verdict, then what? The court-appointed bailiffs are pretty useless and actually getting the money that the court says you are owed can be much harder than winning in court.
You get the claim sent to the high court for £60. Then High Court Sheriffs have much more powers.
This is true, they do - but this is another process that takes time to implement but even with the best bailiffs in the world, what assets can they take? Answer: Only those belonging to the debtor (in this case the company itself).
Bailiffs are not the answer here. It will take months before they get into any premises (original court ruling + initial bailiff notice + initial rubbish bailiff + high court ruling + more bailiffs + `last resort' forcing entry) and once they are inside the company premises all they can take are assets that belong to company - I don't know what people are expecting those to be but I somehow doubt the company haven't thought about this already. I'm not sure what the rules are about bailiffs and company debts - the assumption here seems to be that the bailiffs can go round to companies as they can individuals.
Lock their bank accounts. You can do this with friends of Putin, you can do this with Alpha.
