I got a call from miss nithya number 9611812977 for prepaid to conversion of my numbers. She offered me Rs295 plan . As i was interested told her to convert and told her that i will b available at home only on Sunday . If verification has to b done they can come to my office or they can on Sunday at my home. She agreed and told that will b done. So only i acceptd for conversion and gave Rs600 and rental agreement document on 23rd of Nov 2012.

But till it has not happened and they are making my verification failed. Also my money is still not returned back.

I want airtel to call me and gave back my money and document. Immediately.
