[Resolved]  Reliance Communications — Reliance prepaid balance

I have been using this reliance prepaid mobile [protected] provided by my company since last 9 months. There are fifteen connections using by differest staff of our company. Means we are very good customer to Reliance.
But my compalin is I have recharged my account with Rs. 500/- on dated 9th of December 2008. Now on 10th of December suddenely i have noticed that my balance is 4Rs. 80 paise only. I enquired with reliance customer care where they told me that they ( reliance) had wrongly debited Rs. 1000/- to my account on 7th of December. So they have credited the Rs. 1000/- that means they taken back.
Now my point is, if you taken back Rs.1000/- which i have not used that is ok but why you taken my money Rs. 500/- which i have charged on 9th of December too.
i have registered the compalin also and i have received the complain numbere SR 82634422 and the person of cusotmer care told me that it was wrongly deducted of Rs. 500/- and it will give to your account within three days.
But after one day that is on 11th of december 2008 i have receieved the SMS from reliance number [protected] that as per the SR 82634422 there was no wrong deduction found from your reliance account. Then I asked for the statement which they denied to furnish me.
Now please help me to recover my money.
