How long for you to make a decision to purchase a house, a car or life insurance?
These stuff drain a lot of money from your hard working job. Most people spend their life time to accomplish these as their life achievements.
In the old way, sale these stuff even is really hard, customer make their decision with their family spending time discuss with colleague, friends and relatives.
Marking these day seams to be different, They contact us directly with telephone, email (I really have no idea how could they have my contact. ) and force us to make decision at that time. They leave us to have only little time to consider, think and synthesise the data.
The only one rules to response with these people are just tell them you are busy and hang off the line.
Most smart phones also provide block unwanted number functionality, use it.
