[Resolved]  Tata Indicom — Changing prepaid plan for existing customer

I had subsrcibe to CMO HONEST 450 plan from tata indicom, which offers t2t unlimited calls,
now they are saying they will put a cap of 2000Min per month!

Never thought of TATA will do such cheat.
I bought 3 hanset of tata to avail TATA to TATA free cal just 7 months back, and now they are saying they will put a cap of 2000 Min per month!

Let me know is it legal to change a postpaid plan itself for the existing customer.

Thanks,
Silpayan.
