We got a sales cold call tonight. I don't bother answering the land line anymore since it's never for me, everyone has my mobile. My flatmate answered and it was a call from Sprint Telecom trying to sell us broadband. When my flatmate tried to fob him off by saying she would check it out online the sales guy responded with "Don't use the Internet, I wont get my commission then".
Here is a tip, if your selling broadband you probably should avoid telling the customer to NOT use the Internet. Also don't beg, I'm not in the habit of signing up for monthly bills based on sympathy and a sense of guilt.
