Uninstalling SQL server 2012 in SCCM 2012

I am facing issues while uninstalling MS SQL server 2012 throw SCCM 2012.Since it is a exe installation settings msi has been targeted to create package. There is no error in SCCM log since Uninstall.cmd completely removes the settings msi. But SQL server remains in the system.

Contents of Uninstall.cmd is
