Pratham Foundation — Repeated phone calls

Address:	Pune, Maharashtra
Website:	www.prathamfoundation.org

I would like to complain against an ngo named pratham foundations who have been calling me repeatedly inspite of telling them not to call me again. I have been receiving their phone calls since about 1 year. When i asked them from where did they get my no. They avoided telling. Latest phone call was made by mr ashish on 17 jun 17 at 11:08 am. He wasn't ready to understand that i'm not interested in donating anything for this ngo and he misbehaved.
Regards
