Tata Docomo — Amount deducted for internet usage on recharge of 250 rs.

Address:

Bangalore, Karnataka

Respected Sir,

I received an sms from tata docomo that If I recharge with Rs 250.I would get unlimited data usage and Rs 222.5 balance.
When I recharged tata docomo sim with Rs.250 , I was expected to receive 1GB free 3g data and there after unlimited 2g data.
After recharge I received internet settings immediately which I saved.

I started using internet services , but Rs 70/- was deducted from my balance. I contacted customer service, They blindly said that this offer is not valid , and there after they are not even responding/picking to my calls to customer service. Please help me get my amount back and data pack.

Thanks,
Avinash
