[Resolved]  Vodafone Postpaid SIM Card — i want my money back

Myself Maukik Solgama.
Before 2 months i have been purchased one postpaid sim card from vodafone store in Rajkot, Gujarat.
At that time i have paid Rs.1400 for my choice number.but later
they have found that one or two years back my father was vodafone user and still he hasn't paid his outstanding bill of Rs.600.so they have told me that u will have to paid first outstandiang billing amount and after clearance of outstanding bill we will give your Rs.800 back.
At that time i was agree for that and they told me that rest of your money you will receive directly by cheque by courier after 15 days.
But after 15 days they told me u will receive your money after 45 days but after 60 days still i have not received my money.
And whenever i have tried to consult the officer they just e mail his higher authority for this.
Please solve my problem ASAP.
