Yesterday I called up HSMP team and they told me that your application is rejected

My first application was rejected because my experience letter was not having all my roles and responsibility given.
This time I took all the letter as per the HSMP requirement from my employer still it was rejected and surprisingly this time I didnt score any point, atleast I should have scored 5 points (age)
Home office have dispatched documents and it may take 4-5 days for documents and rejection letter to come to me, but I would like to know if any1 has face the same issue before or what could be the reason why no points were awarded.
thanks
