NEVER answer any calls from numbers/people you either don't recognize or are not on your contact list. It can be difficult to ignore a call, but you will get used to it.
If the person calling you needs you that badly, they will leave a voice message; if they don't bother leaving one, you likely didn't need to hear from them in the first place.
IF YOU DO ANSWER, and the caller is a spammer, it's likely your number will get logged as one which will get answered, so anticipate spam calling to increase (at least in the short term). Additionally, companies sell information to others for numbers which result in answered calls, so also bear that in mind.
In your case, it appears the callers were the victims of Spoofing. Indeed, THEY, shouldn't have answered the call which appeared to be calling from your number.
The thing is, there's still a lot of people who feel they MUST answer a ringing phone - whereas the rest of us only answer expected calls or folks on our contact lists.
To each their own, I suppose. 🙂
