You ever get a call from a number you do not recognize and have trouble looking it up? You don’t want to call them back in case it is some kind of a scam company, but you are irritated that they did not leave a message. I have used search engines, but a good reverse phone lookup is better. Lots of times it is obvious it is a wrong number. When I dial a wrong number and the voicemail comes on, I wait and leave a message advising that I made a mistake. I do this so the person I called does not get paranoid of why they are getting a call from a strange number.
I don’t like getting calls from numbers I do not recognize, so I put people’s minds at ease when I dial wrong. Most of the people I call are already in my contact list, so making errors is not a common occurrence. It happens when I look up a number online and make a mistake in entering the digits. Some people just hang up if the party they are trying to reach does not answer. I am courteous and explain my mistake. A funny thing happening to me was when I was getting regular calls from a person looking for their child. I would advise the person I was not the person they were trying to call, and the person would talk with me for a bit.
There are some reverse phone lookup services that yield pretty good results without charging you anything. I am surprised at what you can find out about people and phone numbers without having to pay any fees. I can’t even imagine what is out there if you pay a service to do a deep dive to get you some information back.
