I called the local Trading Standards office, but apparently Wolverhampton doesn't have a department for Business related matters. Also, because it's a business realted matter in the first place, the laws are slightly different.
I have also contacted the local 'Free Half Hour Consultation' Solicitor and am expecting a call-back from them some time soon.
This is now the third week I have been unable to work, fixing my computer for free is a given and does not cover the monies lost due to inability to work. Solicitors are a must.
Hopefully this wont go to court. If it does, I'll just go with it.
