As notice period is something which both the parties are agreed, a change in that also should be agreed by both the parties. One party can not take a decision and say the other to agree. If you have not received any mail or any other communication in explicit manner, HR of your company is wrong and the officer can not force you (may request) to serve notice period of 90 days. This is an unfair practice and a clear violation of contract terms
2. Normally when companies changes the notice period rules (Eg:- 45 to 60), then for all newly hired employees, the appointment order will be issued accordingly. All other employees continue to have 45 days notice period. After a few years company may increase it to 90 and this is for the new set of employees.
Companies having lazy HR and no clue on employee engagement and happiness will do all these repair work and expect magic. My recommendation is serve whatever period and get relieved from your current establishment. More debate with this kind of people will load you full of negative energy.
Also when you join another company, understand the company, their business, values, culture, talk to a few employees, see the visibility in social media, glassdoor, and not just get convinced by the interviewers or HR or a heavy offer.
Please check if the official communication is received on this either by your HOD or the notice board display has been made or a HR manual revision has happened before going further.
If you are sure the information is not passed then you can give an official email on that and leave at your relieving date.
It is understood and agreed that this appointment, after confirmation, may be terminated by either party by giving to the other at any time, notice in writing of one month. The termination shall take effect at the end of such notice period.
Other Terms and Conditions

The terms and condition contained herein shall be read along with the instruction, guidelines. policies etc, and amendments thereof as presently applicable to you and as may be amended from time to time and as may be made applicable to you by the company subsequently during the course of your employment.
if so you are penalized for absconding.Although my talk you feels stiff but this quiet right. Please look it seriously and then decide to leave in one month but if you known please fallow the hr as per she he say
thanks and regards

To be a valid agreement it requires mutual consent. You are right, but at the same time you have also agreed on a blanket clause providing for applicability of service rules, regulations and policies of the company. So there is an arguable point in favour of enforcement of three month notice period.
