You should first approach the seller of the item. Then, get in touch with the relevant consumer agency. If neither of the previous provides adequate results, a lawsuit can be filed or you may use arbitration. Approach the Seller Compile all necessary evidence such as canceled checks, receipt, photographs showing the issue, a warranty, bill of sale or contract. Determine your goal. Would you like the product replaced? Would you like a refund? Are you just looking for an apology? Schedule a meeting with the manager, customer service representative or other appropriate people by calling the store or service provider. In this meeting with the individual, describe as clearly as possible the nature of the issue and what your goal is. If you can only speak by phone, write a letter as follow-up and keep detailed notes of the dates and with whom you spoke with. It is important to note that if there is a valid warranty for the product, it is best to follow-up with the manufacturer and not the merchant. Take the issue to a higher level, if this doesn't find a solution. This could be the corporate president or supervisor. At this point, you should put your complaint in writing if you have yet to do so. This letter should detail your name, phone numbers, address, and account number (if applicable). Include the date and place of purchase as well as the model and serial number if a product is involved. Concisely describe the issue at hand and the process you have gone through so far to reach a solution. Lastly, you should include what outcome you want and state a deadline for this outcome. Keep a copy of the letter for yourself and include relevant copies of documents. Make sure you keep the originals and retain copies of any correspondence you receive from the company. Get in touch with an agency If your desired goal has yet to be reached, you will want to look in the phone book or online for a consumer complaint agency, such as the county, city or state consumer protection office or the Better Business Bureau. Another option is to go with the trade association method. There are industry trade associations that will offer to aid in mediating issues with regards to their members. You may want to get in touch with the appropriate state-banking regulator if your issue deals with a bank. If an insurer is involved, you will want to get in touch with the state insurance regulator, for a securities problem contact the securities regulator or for utility problems contact the public utility commission. Call the state-licensing department if you the issue deals with a state-licensed trade, such as a plumber. Research the lemon laws of your state, unless you reside in Arkansas or South Dakota, by getting in touch with your state consumer protection agency in the event that you purchased a bad used car. Get in contact with your area postal inspector, whose information can be located in the U.S. government section of the telephone book, for issues that pertain to mail order or mail fraud. Look into finding a local television news program hotline for resolving consumer complaints. Filing a lawsuit When there are no more options, you will want to file a court case in either small claims court, if the amount is small (usually less than $5000) or if not, a regular lawsuit. More than likely speaking with an attorney and having them draft a letter to the merchant or service provider giving the details about the lawsuit will resolve the issue. You probably won't need to hire a lawyer if a small claims case is involved. If the case is bigger than small claims, you will want to hire a lawyer.
