BSNL HOME 345 Combo Monthly Broadband Plan issues

Guys, I have BSNL broadband which I use when I am at home (and I am at home very rarely) . So it was just 1GB plan of Rs. 299 but today I see that in latest bill they have charged it as BSNL home combo 345 plan and charged RS. 345 for it. So it is now 345 per month. But when I looked over BSNL website for details, there is no such plan on their website.

They do have Rs. 375 plan combo with 1.5 GB limit but no sign of 345 plan.

Any idea or link where I can get more details about this plan ?

It could be same old plan of 1GB limit but with new pricing.

I don't know why BSNL is digging their own grave by such ridiculous moves and services.
