Consumer Redressal

Dear Concern, I have taken a Vodafone postpaid connection 7/8 months ago, wide mobile number-9932009465. Now my problem is that mobile service provider not providing my any bill of my usage. Earlier they told to me that they will sent to my residence address but i haven\'t received received any bill in my billing address, then again i complained to their customer care they assured me they will sent me on my registered email address, but they never sent any bill. I have complaint several times but not getting any valid information. Last month they have charged Rs-500/- unnecessarily in my bill. when i asked them they told that i have used that service so they have charged, but i know that i have never used any unwanted service. Again I asked for the bill they told me that i will receive the same on correct time. I requested them to please migrate my connection post to pre paid, still they are not co-operating with me. requesting your kind help in this matter,
