And i was busy witg another patient. At 9p.m i left the office, before that i submit my cashscroll to night staff and forgot about the doller. Next morning i remember about doller and called in office but dollerare not there.. I came to office at 8.30a.m ,watch the cctv footage, aome suspicious movment are there of night staff... But views are not clear as happen between two papers, so only view theee White papers, i hv informed to upper level, i hv wait for full day and lastly say u go now i ll come on Monday, i came on Monday, wait for 4 hours again they asked the same stories, i force them to call up to police but says at first Internal investigation done dn we take a call from external, after a week they call to police,since that its not clear as night staff also deny his blame. Manipal say i can't join the office and i can't quit it... Ans they didn't pay me so how come I survive in delhi. Pls help me out.
