I called mine daily for several weeks - calling back if they were 'busy'.
At the time I wasn't sure if I was just doing it to make myself feel like I was progressing things. As the process went on, it became clear that if I didn't chase them on stuff constantly then it just wouldn't get done.
oh don't worry we already had that.
few weeks in our solicitor went away for 2 and a half weeks. we got passed back to her when she got back last tuesday when she 'got back'.
