call spoofing : i've been attacked

Hey everybody, i'm running a small marketing company using google ads as business model for making benefits. Recently i received calls from real people who thought we had a missed call with them, which is was not the case.

So i'm receiving 10 calls like this from genuine people who thought i've done a missed call to them. I'm suspecting a hacker faking my own caller ID to send automatically missed calls to genuine people.

Could you please give me more informations about that, is it costly to run a hacking like this, is it hard to do it, are there only good hackers for knowing to do that. Help me please.
