Also, OP, have you ever worked in a vet clinic? The one I worked in would take hand written notes of calls from patients and give them to the vet (or whomever needed to return the call). There are so many reasons your return call could be going to your home number instead of your work number:
- by the time the vet gets the message they assume it’s outside work hours and call the home number
- they see the gist of the note and just pull up your file, which has your home number listed
- the note taker wrote a number wrong or the vet read it wrong, and when that number didn’t work, they went to your home number.
Regardless, call or email and put a note on your file that says “use this number between the hours of x and y, otherwise use this number” or “please email invoices to this email address”. So simple to take care of.
