Teleperformance — manager told me you will join soon and then reject me

I have given interview in teleperformance thought consultancy.I have given 2 rounds and in the 2 nd round of interview the oops manager told me interview is good from her end and she will talk to the recruitment team regarding this .After 2 days I contact the consultancy and the peson of consultancy told me i got selected so I was asking for offer letter so he said to me you will get it after lockdown and now suddenly the consultancy person told me your unable to crack the oops round .I am asking what's the wrong means what is the issue he does not tell me anything.He forced me to give another company's interview.Teleperfomance not giving correct information to consultancy or consultancy is fake.in opps manager round she told me everything about process.
