they are unnecessarily disturbing us everyday from past 5 months regarding the airtel landline bill which was already surrendered with the sim on date 2-01-2010. we had already made the outstanding payment still they are generating the bill. i dint understand that when we have already surrendered the sim then why are the sending us the bills for every month. there was a telephonic conversation also but still they are continually disturbing are harassing us. so i request the jury to please see to this issue as it is getting annoying everytime.
