McDonald's official customer feedback platform, MCDVOICE, asks customers to complete a brief online survey at www.mcdvoice.com within seven days of their visit. After choosing either Spanish or English, consumers are asked to input the 26-digit survey code that appears on their receipt. By filling out the MCDVOICE survey, McDonald's can improve customer happiness and service quality throughout its international restaurant network. People who take part get a special validation code in return that they can use to get benefits like a "Buy One, Get One Free" sandwich deal. The survey method available at www.mcdvoice.com is quick, safe, and designed to ensure that every consumer opinion contributes to the ongoing development of one of the most well-known foodservice companies in the world.
