Airtel — to disconnect my airtel number

Address:

Pune, Maharashtra, 412101

I have called customer care executives to disconnect my number ([protected]). They have raised a service request on 22nd of nov. Service request no is sr[protected]. Still the connection hasn't disconnected. Since my connection is postpaid they need to continue the service as much as possible. If this is my situation, then how can i recommend airtel to my friends, family?? Please disconnect the service immediately
