SBI General Insurance — Stop off auto renewal

Address: 741201

I have opted for a health insurance policy from sbi general insurance on 29/05/2015. Though i did not choose the option of auto renewal, yet they deducted the premium of rs.2500 on next year i. E., june 2016.
Several times i have requested them to stop the auto renewal of my health insurance policy, but unfortunately they did not respond to my request.
My sbi general health insurance policy no. Is [protected].
