Regarding Capgemini onboarding

Hello guys, While giving interview for Capgemini, HR asked me to upload documents for 2 job posting because for 1st job posting documents were not uploaded. Due to which offer came for both job posting. I rejected from one job posting and accepted other. Due to this Other job posting HR called and scolded and said offer will be rejected for both jobs.

But the 1st job posting HR said to tell him she told to do so.

Right now portal shows offer is accepted.

Not sure what to do. Help me
