Grant Funding Source review: harrassing telephone calls 1

I requested information about government grant money but when the grant funding source called me I was no longer interested and told them several times to take my name and number off of their calling list. They have called me over 40 times in 7 days. Today I again advised them not to call me anymore and asked to speak to a supervisor. The caller hung up on me after refusing to transfer me to her supervisor and continuously asked me why I was not interested.
