Vodafone India — incoming calls caller id not working

Hi,

I am in a corporate plan with claris lifesciences limited and am am post paid customer of vodafone.

My number is : +[protected]

Off late, i am facing this issue that all incoming calls are shown as “unknown”and i cant see the number of the person calling. Also, the incoming call number is shown unknown even if the contact is in my phone book.

I called vodafone care but didn’t get any solution, i visited vodafone care office but that also didn’t help.

Therefore, request you to take up the matter and help me resolve the issue at the earliest.

I sent mail to the customer care but no reply, i changed the sim but the issue is not resolved
