I diald 123 and received an offer. 94 rs 3 gb for 28 days. Tata docomo gave me option to subscribe from my balance. I recharged for rs 94 from balance. And i received 2 gb for 7 days only. Means 1 gb less i received and instead of 28 day only for 7 days i received net balance. My tata docomo mobile no is [protected]. I m trying to complain from 5 day but not getting any satisfactory solution. Please solve my problem as soon as possible.
