Airtel — annoying calls from[protected]

Hi

Am receiving unnecessary calls from[protected]. There is a lady calling and asking for someone named sangeetha. I informed her twice she got a wrong number but she doesn't seem to understand

The lady is repeatedly calling me and now her tone and mode of communication is irritating. Looks like someone has given my number to her incorrectly and she doesn't understand that at all

I have blocked the number but i want to register a complaint
