Waiver of notice period

I am working in a public sector bank as manager and a mother of a six-year-old kid. I managed to get one reliable maid and she was taking care of my kid after school hours. One day she left the job without any intimation and i couldnt make any alternate arrangement. So I decided to resign the job. Last month I gave resignation letter with a request for early relieving citing my ill health and personal problems on 2.05.17. But I didn't receive any communication from my bank. on 08.05.17 I wrote to our regional office that I will not be able to work after 15.05.2017 due to the emergency situation at home and requested the bank to relieve me by 15.05.2017 and offered to pay compensation for not serving notice period. In reply for the same, our HR department informed me that officer herself can't decide the relieving date. Early relieving is subject to the approval of competent authority. i had left with no other option but to take my kid to work as summer vaccation started on 15.05.2017. I am working in a rural branch in UP where there is a continuous power failure and we had to sit inside bank even without a fan in this hot summer. My kid was not able to sit in the branch due to suffocation and he was complaining continuously that he is not ale to breathe and feeling nausea. That day I got system generated exit alert which mentioned the procedure to be completed before relieving. Considering the difficult situation i informed all the concerned officers that i will not be able to continue in the service due to personal issues and to relieve on completion of all the formalities and to debit my account for not serving notice period. But i havent received any communication after that. I contacted our HR coordinator who informed me that i won't get proper relieving and experience certificate if i don't serve notice period and for early relieving CGM approval on RH recommendation is required. So i went to my branch and gave written request to waive the notice period. My branch head sent a recommendation mail with a scanned copy of my request to the Regional Office. Now my branch head informed me that Regional head is angry on him for recommending my early relieving. I am in a very desperate situation now as i need to try for some other job which suits my conditions and i am not getting proper relieving from the bank. Kindly guide me what can I do to get a proper relieving.
