NO RESPONSE FROM 702

What will it take for someone to give me the e-mail address of Wendy who was on air about 10 days ago at 2.30 am - possibly a recorded programme. She assists people who have been talked into contracts with MTN and Vodacom. I have written twice on the online contact form, I have phoned, I have e-mailed the address given when calling 011 883 etc. The programme invited listeners to call the station for Wendy's e-mail address. Absolutely no response from 702.
