Whether negotiating in person or over the telephone, here are a few tips to keep in mind. Introduce yourself pleasantly to the person helping you with your problem. Keep the tone of your voice pleasant. Keep a positive attitude in your mind as well as in your voice. Be optimistic about the ability of this person to assist you in resolving your problem.
Courtesy goes a long way, too.
State your problem and what you want done concisely. A simple, clear statement of the problem and your proposed remedy is an effective approach. The person who is assisting you may be authorized to offer you certain options. If these are consistent with what you wanted, then your problem has been successfully resolved. If the solution offered is not what you had in mind, you should consider it as an alternative.
