Capgemini — Regarding Second round interview scheduling

Hi my name is Marshall Desouza A, I attended Capgemini face to face first round interview on march 6 2021, HR called on 22th march said I was selected and will schedule the second round interview on 24th March 2021 . The second round interview was scheduled on 24th March 6.00pm - 6.30pm, but when I attended the interview no interviewer was available So HR told me she will reschedule the interview for some other day when the interviewer will be available. But its been 2 weeks i didnt receive any call from HR when I try to call HR she is not picking up the phone . Can you please help me .
