Dear Mr. Shiva,
I would like to inform you that the STV 25 (Juice Up) is available as stated on the website. Probably the retailer you approached might not be aware of this. In the retailer SIM card given to retailers there is a sub-menu called 'SPECIAL RECHARGE'. If they recharge through regular recharge sub-menu it will be considered a talktime value since Tata DoCoMo E-recharge for talk time is not fixed.....you can recharge anywhere between Rs. 10 to Rs.10,000. So what ever value he enters in the regular recharge sub-menu, whether it's 25 or 75 or 777, it will be considered as talktime by the server program. So the next time you visit that retailer, please tell him to recharge through SPECIAL RECHARGE sub-menu and insist that if he makes a mistake, you'll not pay him.
If he says he doesn't know what a special recharge sub-menu is, then please tell him to "go to that sub-menu from where he does that Rs. 51 recharge", which every retailer does immediately after activation of a new number. I think you got this. Should you face any problem with regard to this, please feel free to post the same.
The third-party retailer segment is woefully un-structured and they don't present with any professional behavior. We can't take the word from such third-party retailers and mistake the service provider for that.
Best Regards
