Reliance Communications — Giving less data then promised

Address:

302011

I checked my offers and found one, which says, "2gb 3g data for 7 days in rs88. i recharged and got just 400mb for just 3 days. i had also emailed the same complaint to reliance office, got no response whatsoever. i am highly unsatisfied as this is not the first time reliance is involved in such a cheap deed, they have done similar things earlier also, which i forgive taking it as a mistake, but now it is too much. please resolve this issue asap.
