What would you do when your toxic/fake friends messaged you all of sudden ?

i have been friends with them many years since I was in high school. I tried to be patient and hope they will be nice people. but years by years , I realized that they became more worst. and made me decided to stop to be their friends. so I deleted their phone numbers, left their groups on WhatsApp, deleted their pictures from my phone gallary. and after I did that. no one tried to message me what was wrong when I left the group. so I assumed that they no longer consider me as their "best" friends. so I moved on for 1-2 months.

after several months, one of them tried to say hi and laugh out of nowhere. i don't find it funny but why that person laughing? other one, said hi and ask if I'm okay. for your information that person wrote without emotion like "I tried to care about you but I don't actually care about you. I just wanted to know if you live with successful already or not." and last person., gave me a missed call. ?

what the hell they want from me? I'm tired to deal with them again.. I don't want them in my life anymore.
