Consumer Redressal

I have a complaint on harassment against Airtel mobile company. I had applied for a post-paid connection. The representative of company visited my home and took 300 Rs. as activation charge and gave a Sim Card with allotted number 8800543666.Number activated on 22nd November 2012 and finally I came to know they activate this no.8800099219 instead of allotted Number 8800543666.just after activation i have got a bill of 351.54 Rs on the very same day. I tried to call customer care many time. Every time they gave me different excuses like they are upgrading their system so they can’t check my detail etc. Till that day I received 5-6 massage from airtel that your bill is 1500 or 1200, pls pay it otherwise we will discontinue your services. Now today on 01-12-2012 my outgoing calls are barred and I still have got same massage that my bill is 1200.So kindly resolve this issue on my fervor. thanks
