Retrieve Company name from the Post in contact Entity - MS CRM 2013 online

Question

Hi All,
We have a feature in the contact entity, on change of a field called call status we are triggering a workflow which will take the current value of the call status field and creates a new status in the Auto Post. So repeated calling and call status by Target
marketing will be captured. 
Below is the Sample
Now the issue i am facing is creating a report out of it to capture # of calls and call status. 
This is the sample report I've created. I am not able to Display the Account name in this report.
Fetch XML used:
<fetch version="1.0" output-format="xml-platform" mapping="logical" distinct="false">
  <entity name="post">
    <attribute name="postid" />
    <attribute name="createdon" />
    <attribute name="createdby" />
    <attribute name="source" />
    <attribute name="modifiedon" />
    <attribute name="text" />
    <attribute name="regardingobjectid" />
    <attribute name="createdonbehalfby" />
  </entity>
</fetch>
Kindly suggest how this can be done.

Hi Jithesh,
Thanks for the reply.
The above code retrieves no data and so no output is displayed, not even a  single record is retrieved.
I previously had tried something similar to this , which retrieved the records but account name it was displaying some wrong data.
Below is that code which I tried.
<fetch version="1.0" output-format="xml-platform" mapping="logical" distinct="true">
  <entity name="post">
    <attribute name="postid" />
    <attribute name="createdon" />
    <attribute name="createdby" />
    <attribute name="source" />
    <attribute name="modifiedon" />
    <attribute name="createdonbehalfby" />
    <attribute name="regardingobjectid" />
    <attribute name="text" />
    <link-entity name="systemuser" from="systemuserid" to="createdby" alias="ak">
      <link-entity name="account" from="createdby" to="systemuserid" alias="al">
        <attribute name="name" />
        <filter type="and">
          <condition attribute="name" operator="not-null" />
        </filter>
      </link-entity>
    </link-entity>
  </entity>
</fetch>
