Accenture India — HR not responding - Talent coach is not reachable

I have cleared the online assessment and the technical round. I also had a call from the HR but she did not negotiate the salary part. Instead she informed me that the talent coach will get in touch with me to negotiate the salary. I have had no response after that. Tried reaching the talent coach several times but there is no response at all. HR said that the offer should be released but she doesn’t know anymore.
