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.
Yeah, this is standard triage procedure for understaffed solicitors. Expect them to go on ‘holiday’ soon as well...
