Su-Kam — mppt new defective

Address: C/o Devgiri overseas vpo mahrana opp vardhman dharamkanta gohana road Panipat near Lcrt school, Panipat, Haryana, 132103

Dukan toll free and other numbers not reachable, i heard sukam is closed and launch with new name su-vastika but, sukam users are facing problems because there is no one to attend or attempt complaint. I have purchased a mppt controller and it has a problem, i tried to call sukam but all in vain. If suvastika takeover then it's should attend all dukan customer
