I had recently changed from home 125 plan to 499(unlimited plan). And bsnl charged me 499 Security Deposit. Now, I shifted to 299 combo plan(no security deposit for this plan). When I called up customer care regarding refund of security deposit(499) they say it will be given back when I discontinue broadband. And I have NO plan to do so........ When is Security Deposit for BB plan refunded ? IS there Any way I can get 499 back ??
