Paytm — Rs 451 Idea 3G mentioned 4.5GB data but given only 1GB data for 3 months

Address:

Lucknow, Uttar Pradesh

I have done recharge of Rs 451 on 9th october 2014 of 3G data pack for 90days. And it was mentioned on paytm 4.5GB data will be given for 90days. But I got only 1GB data. IDEA customer service centre is not willing to give me additional data. And telling it is ''paytm'' fault we do not have any such recharge pack. So what paytm can do about it now. ??
