No reply to relive mails(resignation/withdraw resignation/cancelling withdraw)Salary also not paid.

I Started my career in a good software company,Chennai.I was getting fixed pay there.After marriage I moved to Bangalore and joined another company.It is variable pay and what I get in hand is less compared to the previous company.In this Bangalore company,at the time of joining,2018 I was asked for 3 years bond,notice period of 3 months.I gave birth to a baby girl in 2019 and served maternity period for 6 months.To say,tomorrow morning is my delivery,till today evening I was workaholic.I requested for work from home as I have to feed baby.After a couple of months,my manager ordered me to come to office.I went back to company,on travel my mom met with injury and hospitalized,was suggested for bed rest.So again I requested work from home on 2019 Feb.In 2019 April I was joined to client,and the notice period was changed to 6 months(orally).On 6Aug 2021 gave my resignation.After 1.5 months my company replied saying I have to work from Office for 3months, as per the updated HR policy to provide KT from office in the pandemic.I replied as the KT like earlier will be given online without any issues and I dint see the HR policy to come to office in the HR document which I downloaded and attached.I dint get any reply from HR for that mail.On Jan25 I got a call from my senior to ask on retaining for client as they are having pressure from my client,(Feb 6 is LWD)My salary was on HOLD for the January month.On 22January me and my family was tested covid positive and my manager was asking me to give KT to another new person as they dint find replacement.I got much frustrated and said,I already gave KT to 5members and your still not finding a replacement in this 6months.From Jan26 to Feb1 I got continues call from my senior to solve my concerns and giving good package which include variable pay,(less comparative to new offer) requesting to support for 8months.I understand their pain in thought of humanity I accepted the offer to stay for 8months and asked them to send a mail.HR told that they will not send mail and I have to initiate it.So I sent mail,saying with the following concerns I'll be accepting to stay till Sep30th and acknowledge me the same with revised pay scale.I dint get any response and waited for a day and pinged my HR.To my surprise she told next week and On top of that when I asked for a date there is no reply after seeing my messages.I waited till Feb9 I dint get my salary or retain letter and then I cancelled the withdrawn resignation due to lack of information or official acknowledgment for my resignation withdrawal and due to lack of reply on the current status,I planned to continue with my earlier resignation plan with immediate effect and submit the belongings in the office soon.Now company is asking me to come to office and serve for 6more months and then my notice period initiates and reliving process.Resignation acceptance mail is also not given & we should not send reminder mails.Legalnotice refused.Help solving immediately pls
