Convergys India — request for experience certificate

Address:

55, Bannerghatta Main Rd, 1st Stage, Araka Mico Layout, BTM Layout 1, Bengaluru, Karnataka 560029, India

Hi team,

I worked with convergys india services private limited, bangalore from march 2003 till june 2006, i need an experience certificate from them which should also include my roles and responsibility. The letter convergys gives is just plain text that this guy worked with this company and we wish him good luck in future. This does not suffice the work i have done for 3 years. Seems convergys has been acquired by another company name concnetrix and i am not able to reach the hr to contact them.
