One of the biggest time wasting activities in phone prospecting or sales ischasing people who say they are interested in your product or service.  They are always very polite and often enthusiastic in their response to your calls.  “Not now, call me back in a month’s time” and when you do, you often get the same response. Although these types of call seldom go anywhere they serve another purpose in as much they they make us feel we are “making our calls” and being busy! The best way to deal with these types of call is to politely ask the person what will be different in a months time? Can I get you any further information,  so you have a clearer view when I call you back then? If you get nothing more than a grunt,  I suggest you use the “Its OK to tell me to go away if you are not really interested” line. This was used by an old client of mine and worked everytime he was strung along! It is so much better that people qualify out if they are not interested, so you can get on with making calls to people who will be genuinely interested in your product or service. However remember that “no” is still good in some respects as research shows that people will say no at least 6 times before they say yes!  However,  there must be some real justification for their delay ie they are really qualifying to themselves that this is right for them.  Good luck with your future prospecting!!
