There is urgency in the offer. I would hate to see you miss out on this once in a lifetime opportunity. A legitimate business will not pressure you into making a rash decision. The telemarketer balks at the idea of sending you the written information on the company. A legitimate business is always happy to make sure you have all the information you need to make an informed decision.
All investments are risky.
Always take your time with financial investments and talk them over with other people. A telemarketer is required by law to disclose the possible risks involved. The caller asking for donations for a charitable organization is unable to answer your questions on how and where your money will be used. All legitimate charities will share with you exactly where your money will be going. They also will provide you with all the background information you need about the organization.
