Sobit associates mansarovar jaipur - AMC not done by sobit associates jaipur

I had opted for AMC **/**/**** for the Kent Ace model from sobit associates.
It's valid for one year but now their contact is not reachable. Moreover,their office is also not present at the given address.
I tried calling the Kent also but they are not taking responsibility saying they don't have any responsibility for AMC.

Actually,I had called and verified from them whether to pay sobit associates or not and they verified and said to pay without any doubt .

Now no one is taking the responsibility
and I am left with no one to resolve the issue.
May be you can help me!!
