Airtel — my incoming calls and incoming messages are stopped

Address:

I recently moved to telangana from Maharashtra. So I thought of changing circle from Airtel Maharashtra postpaid to Airtel telangana. I went to Airtel store Godavarikhani and bought sim new telangan postpaid sim as he informed me after 7 days if signal will disappear in existing sim then please insert the new telangana sim but my sim signal does not disappear rather my incoming calls and incoming messages are not coming and if any one calls it says phone number does not exist. I tried contacting Airtel customer care, nodal department no one helped me still I am unable to receive my calls and incoming messages to my mobile no [removed]. I really don't know what's wrong with them. What a stupid service they are providing, the worst part is they activated outgoing calls as usual to generate bill.when I contacted Airtel store they are saying it is still showing port in pending buy already 8 days over
