About My Resignation Letter Or Contact Papers

I am a store incharge at an optical store they have 2 branches & 9 employees there I signed a contract that at the time of resigning I have to give 2 months notice period or compensation money. At that time at our official WhatsApp group they send me a notice for 20 days suspension & say " forAs per today's incident management decided to suspend, due to her unacceptable gesture towards organisation" Now after that harassment I don't want to do duty there not even a single day what I should do.
