text: Tony: hi Mark, remember ages ago you said you had a problem with your shed? what was that again?
  Mark: Hi, it was slightly sinking on one side
  Tony: ah we have the same I think
  Mark: oh crap, that's not cool 
  Tony: who did you contact in the end? or did you fix it yourself?
  Mark: we tried but it was too big a job so I got a garden man out to sort it
  Tony: Were you happy with them? 
  Mark: yeah, sorted it quick enough, do you want his details?
  Tony: yes please
  Mark: Janice, I don't seem to have his number, do you?
  Janice: <file_contact>
  Tony: thanks both
target: Mark had a problem with sinking shed. Now Tony has the same problem. Janice sends a contact to a garden man who fixed it.
