I was contacted by Airtel executives over the phone to get my pre-paid connection changed to post-paid connection with the same mobile number. I agreed, and Airtel executive Mr. Chandru visited my residence on 27th Feb. 2009, and collected the required documents and handed over a Post paid SIM for Rs 248/- plan, bearing the number ----------- after which I paid him Rs. 300/- towards deposit. I was told that the SIM shall be activated within 2 working days. Till date it is not activated. I contacted the Airtel outlets and got in touch with Mr. Sunil, as I was not able to reach Mr. Chandru. Mr. Sunil assured me that within 2-3 days it shall be enabled, but nothing has happened till date.
