Billy the first rule of handling an objection is to agree with the objector, unless you do that, you have lost before you start.
not interested - I understand what your saying mr potential client, but with the postal service the way it is, it helps us to at least know that all the mail outs are actually received, n fact that is part of my job to make a not of just how many get lost. So I take it that you received yours then did you? YES/NO if yes, then 'excellent, let me just make a note of that (the wait is to distract the client and throw them before you attack again) erm I mean guide them gently along your path lol So what did you think of what was on there then? (open question he has to carry the conversation now.
whats this regarding - As I mentioned I am calling up to confirm that you actually received the mail out that we sent part of blah blah
i dont do business over the phone - And I don't blame you mister potential money cow (oops I mean client)

I am actually not able to conduct business, other than to check out a few things and make sure all is well. In fact part of my job is to ensure that the mail is conducting ITS business properly, which is why I asked if you received the mail. We always mail stuff out because we know how many people there are who just like you prefer to have something in writing. So what did you think of it then? (assume he had it) go on as above
what are you selling - Hi mister potential client, I am actually not selling anything myself, I am just calling to make sure you received our stuff. I am not a salesman, I doubt I could sell a glass of water to a thirsty prairie dog. Not that he could buy one, as they don't have any money, and if they did they probably wouldn't have it with them as they have no clothes which means no pockets to keep the wallet in .
is this time share - Glad you asked that, what do you know about time share (I know I dont want one CLICK)
im to busy, my schedule - I fully appreciate that your busy, which is why we mail things out so that you have time to look at them at your leisure. I know how busy life can be. But sometimes we just have to step back and take a big breath. I know I did, and it worked for me. So anyhow blah blah.
i already have a time share. - Sorry on this one there is nothing I can help you with, as it depends on what your company policy is on existing purchases etc. That said --- So you have a time share then huh, guess you don't want another lol. Hey where abouts is it? how often do you go there then I bet you have some great times there, how long have you had it blah blah (all open question) let them tell you howmuch time they spend there. find out if they have vacation time apart fro the time they spend there . If yes then why not have two?? :-)
Not that I know about time share though, as I have never been involved, but selling is selling, and I did ok at it ;-).
I actually wrote some articles about selling and posted them online for people like yourself
