Vodafone India — spam calls on my mobile number

I am getting spam calls from mobile number [protected] and [protected]. When i take the call he don't say anything, and keeps silent. After that i search this mobile numbers details on truecaller and it shows these are spam numbers. I want to register a complaint for these mobile numbers as i am continuously recieving silent calls from these mobile numbers after 2 to 3 hours. Thismy first complaint so if i did any mistakes to write a complaint then forget it.
