[Darpak]

I am a business man and i am having Airtel connection with me.Whenever i am having meeting with my clients i am getting a promotional calls like sir do you need a loan or a credit card etc and sometimes from company ends to for special scheme because of this i am suffering a lot and it usually some from one specific number only. Does anyone know how to block a specific number. I would be very thankful to him.

If you are using Airtel connection then i would suggest you to call Airtel Customer Support and tell them to add your number in Black list and say it that you are having corporate user. They will take your request and it would take near about 45 working days for changes to get effected.

If you want to block your number then you can contact your Local Airtel Gallery or private organization where you can register registered yourself in Don't Disturb list and for registration you have to pay a nominal charges for that.
