Am I doing something wrong in my business?

Emma

I have a side-business where I remove/rescue honey bees from peoples homes (for free!! the business side is selling the honey the bees make) so that the homeowner doesn’t have to hire an exterminator to kill the bees. I get a few calls a week from people who have bees, and I ask them for a pic of the bees to confirm it’s not a wasp/hornet/some other insect, and I set up a time that week for me to come remove them. But when the time comes, they basically ghost me! So I don’t know what they’re doing with the bees... I’m the only one around who does this for free. Can anyone offer advice to get more call backs, and less flakes?! I seriously don’t know what I’m doing wrong here 😩
