Airtel — no incoming call facility

Since past 5 days i am not recieving any incoming calls. I had lost my phone few days back and had blocked my number after theft of phone, then when i unblocked my number and inserted the new sim of the same number to new phone, the outgoing calls are working but i am not recieving incoming calls despite calling the airtel customer care several times. Everytime i called they would say we are working on it and it will be resolved by an hour.
Whenever i try calling my phone it comes as the airtel has bared ur number despite of calling the airtel customer care several times to unblock my number. This is causing me a lot of inconvineance. Please look into this and solve my problem soon as possible.
