Rude over the phone

Woolworths called me and tried again to sell me things. The moment you say that you are not interested they just hang up the phone. I am very polite while talking to them (especially in front of my clients) but they become very rude once they hear you are not interested. #1 Dont call me and try and sell me products again over the phone. #2 IF you call me try to get you manners straightened out before you contact a client.
