I used to be in telemarketing for beauty products . I ' m a guy that doesn ' t know the blush from mascara but in 2 weeks I make 30 sales of R 600 to women without anything . I mean no bank account . Living off of their children . I hated everyday of it because that money is better spent elsewhere . Telemarketers are given a script and for every complaint or objection you give we are trained to give 3 counter points to that . It is highly effective but if you want them to never ever call you again say to them clearly please remove me from your systems . After that that company is not allowed to call you . Also check up your rights when it comes to Telemarketers . If you ask where they got your number from , what company they are , what product they are selling and how much it will costtip ask them all in quick succession they have to answer and that pulls them away from their scripts .
