I hate it when people don't call back in a timely manner. I can understand if emergencies come up, but if you have no reason to avoid returning a phone call, it's just plain rude.
Now, my family's pet sitting business has probably lost a lot of potential clients this past year because of phone calls that weren't returned. But why did we not return these phone calls? Because our phone service screwed up big time:
1. We had a separate voicemail box for the business as opposed to our home voicemail. However whenever someone called for the business, the phone would only ring twice, which is barely enough time to get to it even if you're near it let alone in another room.
2. We recently discovered that the voicemail system was completely whack. A woman called and left a message about pet sitting while she was on vacation. She left the message on July 5th. The voicemail inbox didn't give us the message until the 9th.
We just went out and bought a good old answering machine. God knows how much bad has been spread by word of mouth just because of a stupid phone service company that couldn't do its own job correctly.
