Users can take Firestone surveys on Survey.Medallia.com and MShare.net, which are both survey company sites. Both surveys require users to enter a 12-digit code from an invoice from a Firestone Complete Auto Care facility.
The Firestone Complete Auto Care customer experience survey on Survey.Medallia.com states that upon completion of the survey, users have the chance to enter a monthly drawing for a chance to win $500 in free services at any company location. Winners are selected through a random drawing. MShare.net does not state before the user begins the survey whether or not completion of its survey provides entry into a monthly sweepstakes.
