This is a bit of a long story, bear with me please.I signed up for MTNL's Triband back in April 2004 (when it was being marketed as ADSL and was being trialled in a few exchanges in Mumbai). Back then the billing for most plans were time-based and not download-based as they are now. I was allotted something called PLAN_RA, which gave me 40 hours of monthly usage for Rs 500 (plus about Rs 75 as modem rent or some such; I don't remember the exact details -- there was no paperwork and it was too long ago). I've been on this plan ever since. I thought of moving over to one of the new plans but kept putting it off since most of my internet use happens at work and this connection is mostly for weekend surfing at home and I couldn't bear the thought of the running around it would involve. Finally, in November 2005 I applied to move to DSL 399. The work order went through and was executed (or so I am told by the monkeys at the local exchange, and they showed me their online system proving so) but when I check my account details on register.mtnl.net.in it still shows as PLAN_RA.My latest (bi-monthly) bill is an outrage -- Rs 4000 approx, when my usage for both the months concerned (November and December) has not been over 55 hours each. Another thing is, the speed I'm getting is something like 64kbps. I think that's part of this blasted PLAN_RA. I've been calling 1504 / the local QCSC / local exchange forever and nobody does a thing about it.It's turned into a nightmare. When I call to complain, nobody at MTNL knows what PLAN_RA is. When I asked 1504 for usage details for November (which are not available online anymore), they say its 0 MB. Obviously, since all plans are now charged on the basis of downloads, their software doesn't reflect this time-based shit that I'm on (though when I log in via register.mtnl.net.in, it shows me the number of hours billed).What I need to do is 1) get the plan changed properly once and for all, 2) get the bill corrected. From taking a quick look at this forum I think the best thing to do would be to make a trip to the Prabhadevi exchange to get the plan change issue sorted out. Not sure about the bill, though. Do I need to get that done at Prabhadevi as well? Does anyone have the name/numbers of the Broadband GM (I'm sure there's no point emailing?). From talking to the local exchange idiots I've got a bunch of numbers of random AGMs and GMs, none of which seem to work.Any help appreciated. Thanks for taking the time to read.
