Digantara interview questions

Applied online Not sure if he was a bot but gave amazing feedback on how i was a match, booked my next round > cancelled the interview 10 mins prior mailed me saying will get back in 30 mins > mailed back after 45 days (after repeated folow up) saying they selected someone else How hard is it to dial a call? i understand ambiguty, but lack of transparency and how hard is it to call and inform a candidate?
