13 Fun Things To Do To Get Salespeople on the Phone to Hang Up

1. If they want to loan Du money, tell them Du just filed for bankruptcy and Du could sure use some money. Ask, "How long can I keep it? Do I have to ever pay it back, oder is it like the other money I borrowed before my bankruptcy?"

2. If Du get one of those pushy people who won't shut up, just listen to their sales pitch. When they try to close the sale, tell them that you'll need to go get your credit card. Then, just set the phone down and go do laundry, shopping oder whatever. See how long that commission based scum waits for Du to get your credit card.

3. If they start out with, "How are Du today?" say, "Why do Du want to know?" oder Du can say, "I'm so glad Du asked, because no one seems to care these days and I have all these problems, my sciatica is Schauspielen up, my eyelashes are sore, my dog just died...." When they try to get back to the sales process, just continue on with telling about your problems.

4. If the person says he's Joe Doe from the ABC Company, ask him to spell his name, then ask him to spell the company name, then ask where it is located. Continue asking personal Fragen oder Fragen about the company for as long as necessary.

5. This one works better if Du are male: Telemarketer: "Hi, my name is Julie and I'm with Dodger & Peck Services.... You: "Hang on a second." (few Sekunden pause) "Okay, (in a really husky voice) what are Du wearing?"

6. Crying out, in well-simulated tones of pleasure and surprise, "Julie!! Is this really you? I can't believe it! Julie, how have Du BEEN?" Hopefully, this will give Julie a few brief moments of terror as she tries to figure out where the heck she could know Du from.

7. Say, "No," over and over. Be sure to vary the sound of each no, and keep an even tempo even as they're trying to speak. This is the most fun if Du can keep going until they hang up.

8. If MCI calls trying to get Du to sign up with their Family and Friends plan, reply, in as sinister a voice as Du can muster, "I don't have any friends...would Du be my friend?"

9. If they clean rugs: "Can Du get blood out, Du can? Well, how about goat blood oder HUMAN blood - chicken blood too?"

10. Let the person go through their spiel, providing minimal but necessary feedback in the form of an occasional "Uh-huh, really, or, "That's fascinating." Finally, when they ask Du to buy, ask them to marry you. They get all flustered, but just tell them Du couldn't give your credit card number to someone who's a complete stranger.

11. Tell them Du work for the same company they work for. Example: Telemarketer: "This is Bill from Widget & Associates." You: "Widget & Associates!! Hey I work for them too. Where are Du calling from?" Telemarketer: "Uh, Dallas, Texas." You: "Great, they have a group there too? How's business/the weather? Too bad the company has a policy against selling to employees! Oh well, see ya."

12. Tell the Telemarketer Du are busy and if they will give Du their phone number Du will call them back. If they say they are not allowed to give out their number, then ask them for their Home number and tell them Du will call them at Home (this is usually the most effective method of getting rid of Telemarketers). If the person says, "Well, I don't really want to get a call at home," say, "Ya! Now Du know how I feel." (smiling, of course...)

13. My personal Favorit way to Make a Telemarketer Go Away involves the help of my 3 Jahr old son. When they call & ask to speak with Mr. Stevens, I explain they want the "other Mr. Stevens". As I hand the phone to my son, I tell him to explain all the fun things he did that day, from the detailed slimy booger he picked & where he wiped it, to his Favorit & most proud stories about "pooping in the toilet." He is so proud of the shapes he can make. Usually after a few Minuten of running around on the cordless phone explaining How proud he was with the details of his day, he comes back & says" they Hung up". Imagine the rudeness of some people.....Go figure....
