Respected sir/ ma'am

This is to inform you that I nitendra singh chauhan, applied and given techm fresher assessment test online successfully. I reached out to 2 ' nd round of test containing two section as cognitive Technical test and psychometric test.
I completed the cognitive technical test and as I headed to psychometric test, the screen was showing " Failed to load test " . I tried multiple times connecting again and again through wifi but all things go in vain.
I was unable to give psychometric test ; and I tried contacting with mettl mercer helpdesk but nothing fruitful happened.
They said that you should contact to organisation/ person.
Kindly help me out in the same, otherwise my 2'nd round of test as a whole(cognitive and psychometric test) will not be taken into consideration.
