Interview at Accenture

I was interviewed at Accenture last month and was informed, my skill round is through. They scheduled a managerial round for me but later cancelled. Then onwards I keep getting a call from them that they want to schedule my MR and I agree for whatever date they ask me to come. But they never send interview invite. I even called back the HRs and they keep saying we will check and reschedule. No response from their candidate query mail also.
