Capgemini — Adapt login credentials blocked / deactivated

Dear Capgemini Sir/Madam,
My name is Mangesh Buktare. I have accepted a Capgemini LOI for an Analyst role. After that, On 10 Feb 2022 I got my ADAPT login credentials. I have started working on modules I have completed 100% all modules but now, when I try to login to ADAPT platform using those credentials, it says the username is inactivated or blocked, My respective allotted username is CAPG2022B11ADA2014 .
I have mailed Capgemini adapt team continuously but i never got proper response. Please tell we what to now? who is the right person to ask? Help me by resolving the issue as soon as possible.
Thank you in advance
