Hi. i got an Email from another user regarding how to follow consumer redressal using the Consumer helpline(he got info from some of my posts).i ask ed hm for more details and he said he wants to complain since the time with MTNL and actual IST is different and as a result, he has multiple logs from 12-8.01 and some usage (about 15 mb daily) is counted. and ihe is on 849NU plan.i have already sent him details.what i want to know is , is the case actually this?? also, if yes, how can one gather proof?coz if proof can be got, this can become a pretty good fight.also, do any other user have same problem?
