PHONE CALLS — Getting phone calls daily

Address:

Gautam Buddha Nagar, Uttar Pradesh

Hi

I am getting daily phone calls from these following numbers:
[protected], [protected], [protected]

I used to get almost 6-7 calls daily from these numbers and whenever I tried to pick it up it got disconnected. I tried to call back them also. However, there is only some kind of music, no one on the other side.

I am getting disturbed a lot from these calls.

Please help me to get who are they and what they want. Why they are calling like this.

Regards
Dipika
