JustDial.com — spam call from justdial

I searched about repairing a device in just dial which is used in my office today in the morning. After sometime I got a call from [protected] and after I picked it up it ends automatically. So I didn't bother about it that much. But in the afternoon I received a call from the same number, this time it was a lady who was speaking and she was enquiring about my device which have to be repaired. After talking for 2 minutes I understood that this lady doesn't mone that much about the device and she is just talking about it. And she told me that she is calling from some company (I dont remember the name exactly). But the way of her talking was not that much professional. After 3 to 4 minutes I heard a kid laughing in the background and immediately I think she just muted me and make the kid go away and she unmuted the call. I found it suspicious so I enquired about the device's repairing and she was not able to give me a clear answer. I felt like she loss her confidence and after some seconds she hanged my call.
I don't know whether they have my personnel details or something. I don't know who she is. It is clearly a spam call and I'm worried about it now.
Didn't expect a fake call from a company which I used to think its a trust worthy one. It was such a bad experience. Nobody wants to risk their personnel information.
I would like to have a solution for this problem in which my personnel data is at risk.
